FIELD OF TECHNOLOGY

Certain embodiments of the disclosure relate to a television content packaging and distribution system. More specifically, certain embodiments of the disclosure relate to a method and system for publishing a disparate per-client live media output stream based on dynamic insertion of targeted non-programming content and customized programming content, and for server-side dynamic insertion of programming content in an indexed disparate live media output stream.

BACKGROUND

Recent advancements in the field of television content packaging and distribution systems have led to a massive development of numerous technologies and broadcasting platforms that are revolutionizing the way consumer devices access and playout media content. Usually, broadcasting platforms refer to the types of networks that are used to deliver the media content to the consumers. Currently, the broadcasting platforms, such as analog terrestrial broadcast, digital terrestrial broadcast, direct-to-home satellite broadcast, cable, Internet Protocol (IP), and over-the-top television (OTT), compete and strive to increase their appeal by gaining and retaining the audience viewing the media content.

Modern streaming protocols, such as HTTP Live Streaming (HLS) and Dynamic Adaptive Streaming over HTTP (DASH), are implemented to support streaming of various live content services, such as DIRECTV NOW℠, SLING TV℠ and PLAYSTAYION™ VUE, to consumer devices. Due to dissemination of such modern streaming protocols in the television, radio, and broadcasting sector, it is evident that the success of broadcasting will be dependent on the ability of the network provider to gain access to the content that consumers demand, and to differentiate their offering from that of incumbent broadcasters or find breakthrough modes of media content delivery.

Existing systems for Server-Side Ad Insertion (SSAI) support live streaming and make decisions to insert non-programing content in near real-time. However, for On-Demand streaming, such decisions to insert non-programing content are made upfront. Further, legacy technology of the existing systems for server-side content insertion support a finite playback buffer as the encoder typically publishes a rolling window having limited duration. Accordingly, amount of control the user can excerpt to influence what non-programming content and programming content is shown may get limited.

Further limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through comparison of such systems with some aspects of the present disclosure as set forth in the remainder of the present application with reference to the drawings.

DETAILED DESCRIPTION OF THE DISCLOSURE

Certain embodiments of the disclosure may be found in a method and system for publishing a disparate per-client live media output stream based on dynamic insertion of targeted non-programming content and customized programming content, and for server-side dynamic insertion of programming content in an indexed disparate live media output stream. Various embodiments of the disclosure provide a method and system that not only provide live channel offerings in cost-effective manner but also provide enhanced, intelligent, and personalized viewer experience to increase their appeal by retaining the audience viewing the media content. Further, additional embodiments of the disclosure provide another method and system that allows for simulation of an infinite live window (or an infinite playback buffer). Accordingly, the user may seek to a desired point scheduled backwards or forwards with respect to a live point in a playback buffer of the first disparate live media output stream, as limited or stimulated by business rules.

Modern streaming protocols, such as HLS and DASH, break media content into numerous small media content segments, typically less than 10 seconds in length. Further, the modern streaming protocols implement manifests that instruct a media player on what media content segment to retrieve and play next. The manifest may enlist the media segments that make up the full length of the media asset. The manifest may include information, based on which the media player at a consumer device may be able to determine the media segments. The manifest and/or media content segment may also include and/or specify additional information to facilitate a media player to transition smoothly between media content streams from different sources. The manifest may be used for creating a playlist of multiple media content files, or for interrupting media content with advertising and then resuming the media content.

Such modern streaming protocols support video-on-demand (VOD) assets and live content as well. The VOD assets prepared for distribution, for example Internet distribution, may have a sequence of short duration segments added to a manifest. The short duration segments may be separate physical files or pointers (real or to be calculated) to the short media content segments inside a larger file. On the other hand, in case of live content, new short content media segments are made available as soon as they are created. In some protocols, each new segment is added to a manifest while in others the media player is provided with information that may be utilized to calculate what the next live segment will be. In the latter case, a signal in the media content itself may be utilized to inform the player when to re-inspect or check the manifest for a change in media content. In live streaming, delivery of live content is supported by making available each new short media content segments as soon as such media content segments are generated. In some protocols, new media content segments may be added to the manifest, while in others, the media player calculates necessary information about the next live media content segments.

In accordance with various embodiments of the disclosure, a system is provided for publishing a disparate per-client live media output stream based on dynamic insertion of targeted non-programming content and customized programming content. One or more processors in the system may be configured to receive a first manifest request from a first client device, wherein the first manifest request comprises one or more parameters. The one or more processors in the system may be further configured to determine a first additional content that comprises a customized first programming content and a targeted first non-programming content for the first client device based on the one or more parameters and the associated indexed metadata. The one or more processors in the system may be further configured to generate a first programming schedule for the first client device based on the selected one or more live input streams and/or the one or more pre-encoded media assets, the associated indexed metadata, and the determined first additional content. Accordingly, one or more live input stream manifests and/or one or more pre-encoded media asset manifests published in a content delivery network and associated indexed metadata may be selected based on the one or more parameters. The one or more processors in the system may be further configured to publish a first disparate live media output stream manifest for the first client device based on insertion of the selected one or more live input stream manifests and/or the one or more pre-encoded media asset manifests, the associated indexed metadata, and the determined first additional content in accordance with the first programming schedule generated for the first client device.

In accordance with another embodiment of the disclosure, a system is provided for server-side dynamic insertion of programming content in an indexed disparate live media output stream. One or more processors in the system may be configured to publish a first programming schedule that comprises one or more functionalities enabled via one or more constraints and rights associated with at least a first disparate live media output stream. The published first programming schedule may reference one or more pre-encoded media assets and/or one or more live input streams. The one or more processors in the system may be further configured to generate an indexed first disparate live media output stream for a first client device based on the published first programming schedule. Based on a playback of the indexed first disparate live media output stream at the first client device, the one or more processors in the system may be further configured to receive a client request from the first client device. The client request comprises at least a program identifier referenced in the published first programming schedule with respect to a playback position in the published first programming schedule. The one or more processors in the system may be further configured to insert manifest data and indexed metadata of a programming content associated with the program identifier to a first disparate live media output stream manifest in accordance with the one or more functionalities. Based on the insertion of the manifest data and indexed metadata associated with the program identifier referenced in the first programming schedule, the one or more processors in the system may be further configured to at least one of alter the first disparate live media output stream or generate a second disparate live media output stream. The altered first disparate live media output stream or the generated second disparate live media output stream comprises the manifest data, the indexed metadata and an updated playback position.

FIG. 1A is a block diagram that illustrates an exemplary system for publishing a disparate per-client live media output stream based on dynamic insertion of targeted non-programming content and customized programming content, and for server-side dynamic insertion of programming content in an indexed disparate live media output stream, in accordance with exemplary embodiments of the disclosure. Referring to FIG. 1A, the system 100, comprises a media packaging and distribution system 102 that is communicatively coupled to published data sources 104 a, . . . , 104 n, Ad decisioning servers 106 a, . . . , 106 n, via a network 108 and/or other programmatic means. There are shown consumer devices 110 a, . . . , 110 n that are communicatively coupled to the network 108. The media packaging and distribution system 102 may comprise at least a DACIS 103, a Content Decisioning Service (CDS) 105, a Content Packaging and Distribution System (CPDS) 107, a stream selection service 142, and a repository of schedules, rights, and user preferences database 144. There are also shown source devices 118 communicatively coupled to the media packaging and distribution system 102 through the network 108. An external data source 120 is also provided, which is communicatively coupled to the media packaging and distribution system 102 through the network 108.

The media packaging and distribution system 102 may comprise suitable logic, circuitry, and interfaces that may be configured to execute code that handles media content comprising audio, video, images, metadata, manifests, and/or other data (embedded and/or externally referenced). The media content may include a video, an audio, a combination of audio and video presentations, and/or embedded or externally referenced metadata, a combination of multiple-audio, multiple-video, and/or embedded or externally referenced metadata. Accordingly, the media packaging and distribution system 102 publishes a disparate per-client live media output stream based on dynamic insertion of targeted non-programming content and customized programming content.

In this regard, the media packaging and distribution system 102 may provide video programming services to viewers, usually for a subscription fee (such as pay television). The media packaging and distribution system 102 also handles distribution, for example, multicasting, unicasting, broadcasting, streaming, for one or more channels to be viewed on one or more of the plurality of consumer devices 110 a, . . . , 110 n.

The media packaging and distribution system 102 may be operated by an entity related to handling or distribution of media content, for example, a broadcast provider or operator, or a network provider or network operator. The entity related to handling or distribution of media content may also be referred to as a content owner, a distributor, a syndicator, a re-distributor, a content aggregator, a search, discovery, or cataloging service provider, or any other entity actively or passively involved with the distribution, cataloging, or referencing of complete or partial presentations of media content. Throughout this document, the terms broadcast provider or broadcast operator, and network provider or network operator may be utilized to refer to the entity related to handling or distribution of media content, interchangeably. The broadcast provider may handle a single channel or a plurality of channels, or one or more networks. The broadcast provider may be configured to distribute content via one or more platforms, for example, traditional over-the-air broadcast channels, radio, cable television networks, satellite communication networks, the Internet, and/or other content delivery networks (CDNs). In this regard, the broadcast provider may be configured to execute code that communicates linear video feeds (also referred to as a network television feed or broadcast feed) to the media packaging and distribution system 102. In a broadcast chain, the broadcast provider may receive actual content, for example, from a production studio, in one or more source formats. Examples of the one or more source formats may include, but are not limited to a tape file, or a live feed that may be further converted to a serial digital interface (SDI) video interface and/or on a high-definition SDI (HD-SDI) video interface for processing and playout. The broadcast provider may further process the content, such as insertion of graphics, closed captions, preparation of programming schedule, insertion of triggers, and the like, and provide final delivery by a broadcasting apparatus. The communicated linear video feed and the playout schedule may correspond to a channel, such as CNN channel that is broadcast to the media packaging and distribution system 102, via a communication network. The linear video feed may be broadcasted as a multi-program transport stream (MPTS) (also referred to as a live video feed) to the media packaging and distribution system 102, via the network 108. The broadcast provider may be owned by (or associated to) a broadcast provider or operator, a network provider or operator, or a content provider or operator.

The media packaging and distribution system 102 may receive the MPTS, which includes the signaling content and metadata, from the broadcast provider based on, for example, current society of cable telecommunication engineers (SCTE) standards (SCTE-35 and SCTE-224) to control web and regional blackouts, network end of day switching, and advertisement insertion. For example, the media packaging and distribution system 102 may be signaled for various blackout types with in-band SCTE-35 message. Further, the media packaging and distribution system 102 may receive program metadata that specifies certain events or operations, such as, for example, when to blackout shows. Examples of legacy distribution system that may be benefitted from the media packaging and distribution system 102 may include direct-broadcast satellite (DBS) providers, cable television (CATV) systems, and other wireline video providers and competitive local exchange carriers (CLECs) using, for example, IPTV.

The DACIS 103 may comprise suitable logic, circuitry, and interfaces that may be configured to leverage one-to-one scale of traditional SSAI systems to support custom programming content choices and not just targeted non-programming content. For example when the user selects to join a live stream, a content decisioning system, such as the CDS 105 could determine that, instead of joining the live stream for the last few minutes of a program prior to the start of the intended program, the user should instead be shown content more relevant to the user so as to prevent them from tuning away, e.g. show a personalized set of basketball highlights and ads to a user who likely joined the stream to watch a basketball game that is coming on next. The DACIS 103 replaces original content in the live stream prior to game start with user relevant content, such that upon its conclusion, the user is seamlessly presented the game.

The DACIS 103 may be further configured to, via a programming schedule or tag indicator in a disparate live media output stream manifest, be notified of one or more content graphical treatment opportunities within the media content. The DACIS 103 may be further configured to make required non-programing content calls on behalf of the plurality of consumer devices 110 a, . . . , 110 n. Accordingly, the DACIS 103 may provide the plurality of consumer devices 110 a, . . . , 110 n with information needed to execute the graphical treatment graphical content via a secure out-of-band channel between the DACIS 103 and the plurality of consumer devices 110 a, . . . , 110 n. In accordance with an embodiment, the DACIS 103 may be configured to include not showing non-programming content that a user of a consumer device may elected to skip or rated poorly in an earlier non-programming content break. Further, the DACIS 103 may enable the user to skip non-programming content as the user interacted with a previous non-programming content or made a purchase and the advertiser elected to sponsor the remainder of the programming content.

In accordance with an embodiment, the DACIS 103 may be configured to provide seamless failover between redundant disparate live media output streams for large events, thus improving reliability. In certain instances, some of the plurality of consumer devices 110 a, . . . , 110 n may support a primary and backup disparate live media output streams and are able to fail between them. In other instances, others of the plurality of consumer devices 110 a, . . . , 110 n may not support the primary and backup disparate live media output streams. In such instances, the consumer devices may attempt to join an alternative disparate live media output stream after occurrence of an event such as a device failure or crash. For such consumer devices, the DACIS 103 may be configured to monitor both the primary and backup disparate live media output streams, and if there is a failure, write the alternative disparate live media output stream into the disparate live media output stream manifest.

Each of the plurality of published data sources 104 a, . . . , 104 n may be coupled to one or more television networks and may comprise suitable logic, circuitry, and interfaces that may be configured to execute code that provides actual audiences for programs that were distributed. As illustrated in FIG. 1A, the plurality of published data sources 104 a, . . . , 104 n are coupled to the media packaging and distribution system 102 via the network 108 and configured to monitor audience drift to or away from a tuned channel airing a live media output stream. The plurality of published data sources 104 a, . . . , 104 n may provide actual audiences for programs to the indexing and storage system 116. An exemplary published data source may be Nielsen. Nielsen has the capability to determine when a viewer watches the same set of media items, for example, advertisements and/or promotional content, in programming data, such as an episode, in a live video feed within 3 days of original airing, and provide Nielsen “C3” credit. Another exemplary published data source may be a published database that provides ratings for a media item, such as gross rating point (GRP). The GRP is advertising or promotion impact measure for each advertising and/or promotional campaigns, known in the art. Other exemplary published data sources may also include direct/indirect access to other public or private data sources (persistent or ephemeral) through programmatic means.

The CDS 105 may comprise suitable logic, circuitry, and interfaces that may be configured to determine, upon request, which programming content (or partial programming content) to deliver back to the plurality of consumer devices 110 a, . . . , 110 n. Thus, the CDS 105 may be configured to insert additional content (including non-programming content) or replace existing content, according to one or more parameters provided by the plurality of consumer devices 110 a, . . . , 110 n and data stored in various external systems and/or databases.

The Ad decisioning servers 106 a, . . . , 106 n may comprise suitable logic, circuitry, and interfaces that may be configured to implement at least an advertisement decisioning component that may be used during a real-time content or advertisement placement activity, for example during dynamic ad insertion. The Ad decisioning servers 106 a, . . . , 106 n may further determine ad-load opportunity, based on targeting data from schedules, rights, and user preferences database.

For example, commercial or non-commercial advertisements may be dynamically inserted within program segments of the live input streams based on the detected upcoming indicator, such as an inbound trigger, a signaling point, and/or a signal in a pre-encoded media asset and/or a live input stream by the Ad decisioning servers 106 a, . . . , 106 n.

In an embodiment, the DACIS 103 may be generalized as a proxy between the plurality of consumer devices 110 a, . . . , 110 n and the Ad decisioning servers 106 a, . . . , 106 n. In one implementation, a request is sent from a consumer device to the DACIS 103. The DACIS 10 may call on of the Ad decisioning servers 106 a, . . . , 106 n to determine a set of non-programming content that may be inserted into the disparate live media output stream.

The CPDS 107 may comprise suitable logic, circuitry, and interfaces that may be configured to index programming content, which is prepared for usage by a system, such as the stream publishing engine 114. The CPDS 107 may further define metadata detailing various facets of the programming and/or non-programing content including duration, known locations and opportunities for programing and/or non-programing content insertion/replacement.

The network 108 may be any kind of network, or a combination of various networks, and it is shown illustrating exemplary communication that may occur between the Ad decisioning servers 106 a, . . . , 106 n and the media packaging and distribution system 102. For example, the network 108 may comprise one or more of a cable television network, the Internet, a satellite communication network, a wide area network (WAN), a medium area network (MAN), and a local area network (LAN). Although a network 108 is shown, the disclosure is not limited in this regard; accordingly, other exemplary modes may comprise uni-directional or bi-directional distribution, such as packet-radio, satellite. Furthermore, the network 108 is an exemplary embodiment of a distribution system.

The consumer devices 110 a, . . . , 110 n may refer to end-user devices or consumption devices where the content is played to be consumed by a user. The number of impressions of a media item, such as an advertisement and/or promotional media, on such plurality of consumer devices 110 a, . . . , 110 n determines the advertising impact or promotion impact and number of actual audiences achieved during campaigns. Examples of the consumer devices 110 a, . . . , 110 n may include, but are not limited to, connected TVs, connected TV with paired and/or connected devices (e.g., HDMI sticks, tablets), personal computer, smartphone, tablet, OTT set-top, or hybrid set-top, and second screen devices such as smartphones, tablets, game consoles, personal computers, set-top boxes, and embedded devices. The consumer devices 110 a, . . . , 110 n may further include process/system that may process the output for any means, regardless of the capability or intent to decode for media presentation, and on which the consumer may launch a web page, a web application, or a web service to view media content.

The source devices 118 may comprise suitable logic, circuitry, and interfaces that may be configured to communicate a live media feed or live input streams of a channel, such as an existing channel, to the media packaging and distribution system 102. In accordance with an embodiment, the live input streams of the channel may correspond to a broadcast feed. The source device 118 may be communicatively coupled to the network 108.

The external data source 120 may comprise suitable logic, circuitry, and interfaces that may be configured to execute code that handles retrieval and storage of audience data that corresponds to subscribers of the plurality of consumer devices 110 a, . . . , 110 n. The audience data may include demographics data, audience targeting data, trending data, device type data, device platform data, and content recognition-based data, such as automatic content recognition (ACR)-based data. The trending data may comprise information on what's trending in the social networks (or platforms), such as Twitter®, Facebook®, and the like. The trending data also comprises information on what's trending based on social engagement, such as number of likes or votes to a particular media item, or number of people watching a particular media item. The trending data may indicate an aggregate interest level of a number of users in the social networks for a particular media item. For example, a thousand or more shares, or likes by a number of users may indicate a highly popular media item.

The stream selection service 142 may comprise suitable logic, circuitry, and interfaces that may be configured to execute code that may be configured to provide a consumer device, for example, the consumer device 110 a, requesting to view the disparate live media output stream with a correct variant of disparate live media output stream, based on the geolocation and identification of the consumer device 110 a, along with data retrieved from the repository of schedules, rights, and user preferences database 144.

The repository of schedules, rights, and user preferences database 144 may comprise suitable logic, circuitry, and interfaces that may be configured to store the schedules for all source feeds, availability rights for all the content in the schedules, regional blackout zones for the various sports leagues, predefined location-based viewing preferences, individual client viewing preferences, and any viewing or transition rules provided by the stream owner operator. The repository of schedules, rights, and user preferences database 144 may further store one or more constraints and rights associated with disparate live media output streams based on which one or more functionalities may be enabled.

In operation, in accordance with an aspect of the disclosure, upon receiving a first manifest request from a consumer device, the DACIS 103 may be configured to publish a manifest of a first disparate live media output stream for the consumer device. The first disparate live media output stream may be chosen by the DACIS 103, at the time of the first manifest request, to best target a consumer device, according to a plurality of client-specific parameters. The plurality of client-specific parameters may comprise user preferences and identifiers, consumer device preferences and identifiers, and one or more rules/rights governed by geolocation data and current position of playback of a first disparate live media output stream at the consumer device. The first disparate live media output stream manifest may be generated, at the time of the first manifest request, to include additional content, such as the targeted non-programing content and the customized programming content. Examples of the targeted non-programing content may include, but are not limited to, advertisements, personalized (per-user) advertisements, video advertisements, and graphical treatment (such as overlays). The targeted non-programing content may further include first interactive elements, such as an option to purchase goods or content, and second interactive elements. The second interactive elements may further affect the generation of the first disparate live media output stream manifest by providing various options. For example, a first option may be to skip a given ad, a second option may be to skip future ads for remainder of the playback of the first disparate live media output stream, a third option may be to choose one or more ads of a given category, or a fourth option may be too watch all ads immediately to avoid ads for the remainder of the playback. Examples of the customized programing content may include, but are not limited to, promotional content, short-form content, or alternate content (content replacing that of the requested first disparate live media output stream.

The DACIS 103 may further receive metadata associated with the content and additional content for the first disparate live media output stream from the CPDS 107. The metadata may include, for example, ad break locations, graphical treatment marker/triggers, SCTE35 markers, content duration, personalized content opportunities, and one or more decision point locations.

In accordance with an embodiment, the DACIS 103 may be configured to convert a pre-encoded media asset to the first disparate live media output stream to facilitate one or more subsequent modifications on the first disparate live media output stream. The one or more subsequent modifications may correspond to a user selection, a user preference, a change in a first programming schedule, or a time or geolocation-based rule. In accordance with an embodiment, the DACIS 103 may be configured to perform another conversion of remainder of the first disparate live media output stream into the one or more pre-encoded media assets to facilitate download of the one or more pre-encoded media assets at the consumer device and mitigate dependency on the DACIS 103 for playback of remaining portion.

In accordance with another aspect of the disclosure, upon receiving the first manifest request, a manifest of the first disparate live media output stream may be altered to include additional or alternate content, apart from the content originally scheduled for playback. The DACIS 103 may be configured to determine which content to include/replace by utilizing one or more parameters. The one or more parameters may include, but not limited to, URL requested for playback, and an identifier referencing a record for an existing first disparate live media output stream or an external connected system, such as the CPDS 107. The one or more parameters may include a plurality of client-specific parameters that may comprise user preferences and identifiers, consumer device preferences and identifiers, and one or more rules/rights governed by geolocation data and current position of playback of a first disparate live media output stream at the consumer device. The one or more parameters may include a plurality of client-specified attributes derived from user interaction with the consumer device. The plurality of client-specified attributes may include, for example, a preference for a given type and/or category (or categories) of programming content, a possible time constraint or duration to fill with content. The time constraint or duration to fill with content may be determined by user preferences from an external system, such as the repository of schedules, rights, and user preferences database 144, a range defined in the first client manifest request, schedule tolerances, as defined in the repository of schedules, rights, and user preferences database 144, device preferences/identifiers declared in the first manifest request, and a prior consumer request, or found in the repository of schedules, rights, and user preferences database 144. The time constraint or duration to fill with content may be further determined by geolocation information declared in the first manifest request or found in the first manifest request, or external database, such as the repository of schedules, rights, and user preferences database 144, or external systems, such as a content recommendation engine. The one or more parameters may further include rules, rights, and schedule data stored in the DACIS 103 or an adjacent, external system—such as the repository of schedules, rights, and user preferences database 144.

In accordance with an embodiment, the DACIS 103 may determine where to place new or alternate content within the requested disparate live media output stream. The DACIS 103 may utilize metadata, such as ad break locations, graphical treatment markers/triggers, SCTE35 markers, content duration, and one or more decision point locations. The metadata may be sourced from a system that has indexed metadata for the asset, such as the CPDS 107. The DACIS 103 may generate a new schedule from the determined alterations in the first disparate live media output stream. The DACIS 103 may transmit resulting schedule to the stream publishing engine 114 to generate a final disparate live media output stream. The final disparate live media output stream may be delivered back to originating client. The stream publishing engine 114 may generate the first disparate live media output stream manifest based on one of a pre-defined conversion modes. The pre-defined conversion modes may correspond to pre-encoded media assets to live stream mode, pre-encoded media assets to live stream mode with scalable architecture, a live stream to live stream mode, and a mixed mode corresponding to switching between pre-encoded media assets and live streams.

The final disparate live media output stream may contain one or more decision points, which, if configured, may be presented by the consumer device to the user. In this regard, the final disparate live media output stream may be delivered as a live stream between the decision points whether or not the programming content selected by a user is pre-encoded media asset or a live input stream. At the one or more decision points, the user interaction may correspond to one of a desired selection corresponding to the user interaction with one or more interactive elements, or a default selection corresponding to non-interaction of a user with the customized first programming content and/or the targeted first non-programming content in the first disparate live media output stream played back by the media player. The desired selection or the default selection may be transmitted to an external storage system that is the repository of schedules, rights, and user preferences database 144.

In accordance with an embodiment, at the one or more decision points, the one or more interactive elements may facilitate exclusion of the targeted first non-programming content or the customized first programming content and replacement by default content. The one or more interactive elements may further facilitate selection of alternate customized first programming content, selection of a subsequent second programming content, approval or disapproval of the selected customized first programming content, and/or exclusion of subsequent second non-programming content for a remaining portion of the first disparate live media output stream played back by the media player. The one or more interactive elements may further facilitate selection of one or more targeted first non-programming content of a specific category, or viewing of some or all of the targeted first non-programming content immediately to avoid some or all of the targeted first non-programming content for the remaining portion of the first disparate live media output stream played back by the media player.

In accordance with another aspect of the disclosure, the DACIS 103, upon the first manifest request, may seamlessly transition the first additional content to an alternate additional content according to determination made by the stream selection service 142, based on one or more transition parameters. The one or more transition parameters may comprise one or more parameters from the first manifest request, current state of the first disparate live media output stream manifest determined based on accessibility, regular update, and suitable encoding, digital rights management, and compatibility with the first client device, rules provided by a stream owner operator, and user preferences defined in the repository of schedules, rights, and user preferences database 144.

The DACIS 103 may retrieve alternate metadata for the alternate additional content from the CPDS 107. The alternate metadata may indicate a location to seamlessly transition from the first additional content to the alternate additional content, and may include ad break locations, graphical treatment markers/triggers, SCTE35 markers/triggers, content duration, and/or one or more decision points. The DACIS 103 may be configured to determine placement of the alternate additional content within the first disparate live media output stream manifest based on the associated indexed metadata and the alternate metadata. The DACIS 103 may generate an alternate programming schedule for the first client device based on the alternate additional content and the alternate metadata. The DACIS 103 may transmit the generated alternate programming schedule to the stream publishing engine 114. The stream publishing engine 114 may generate a final disparate live output stream manifest for the consumer device.

In accordance with an embodiment, the DACIS 103 may revoke the first disparate live media output stream manifest published for the first consumer device based on an identifier primitive associated with the first disparate live media output stream of the first consumer device in an instance in which a media player of the first consumer device is determined to be a plagiarized media player with unauthorized access to content. In such embodiment, the first disparate live media output stream may include at least one unique identifier inserted by the DACIS 103.

In accordance with another aspect of the disclosure, the DACIS 103 may be configured to receive a client request from a first client device, such as the client device 132 a, based on a playback of an indexed first disparate live media output stream at the first client device. The client request may comprise at least a program identifier referenced in the published first programming schedule with respect to a playback position in the published first programming schedule. Accordingly, manifest data and indexed metadata of programming content associated with the program identifier may be inserted to a first disparate live media output stream manifest in accordance with the one or more functionalities. Based on such insertion, the DACIS 103 may be configured to at least one of alter the first disparate live media output stream or generate a second disparate live media output stream. The altered first disparate live media output stream or the generated second disparate live media output stream comprises the manifest data, the indexed metadata and an updated playback position.

FIG. 1B is a block diagram that illustrates an exemplary DACIS for publishing an updated disparate live media output stream in mixed mode based on user selection, in accordance with an exemplary embodiment of the disclosure. Referring to FIG. 1B, the DACIS 103 comprises a first programming schedule 111, an alternate programming schedule 113, a stream publishing engine 114, a personalized experience manager (PEM) 115, and an indexing and storage system 116.

There is further shown a per-client disparate live media output stream 117 a, . . . , 117 n for corresponding client device from the client devices 132 a, . . . , 132 n.

In some embodiments of the disclosure, the stream publishing engine 114, the PEM 115, and the indexing and storage system 116 may be integrated to form an integrated system, as illustrated in FIG. 1B. In some embodiments of the disclosure, as shown, the stream publishing engine 114, the PEM 115, and the indexing and storage system 116 may be distinct. In this regard, the PEM 115 may be implemented external to the DACIS 103 without loss of generality. Other separation and/or combination of the various entities of the exemplary media packaging and distribution system 102 illustrated in FIG. 1B may be done without departing from the spirit and scope of the various embodiments of the disclosure. In an embodiment, the implementation of the DACIS 103 may be on the server-side. In another embodiment, the implementation of the DACIS 103 may be on the client-side.

The first programming schedule 111 may correspond to an instruction set for a disparate live media output stream for a corresponding client device. The first programming schedule 111 may inform the stream publishing engine 114 about pre-encoded media assets and live input streams as well as when and how to switch between the various pre-encoded media assets and live input streams. The first programming schedule 111 may also support defining break durations for mid roll ads, break locations, and durations in the pre-encoded media asset and live input stream switches.

The alternate programming schedule 113 may correspond to an instruction set for an updated or alternate disparate live media output stream. The alternate programming schedule 113 may inform the stream publishing engine 114 about the alternate pre-encoded media asset and/or the alternate live input stream, and alternate additional content. Specifically, the alternate programming schedule 113 may indicate that when and how to switch between the various disparate live media output streams.

The stream publishing engine 114 in the DACIS 103 may be configured to generate disparate live media output stream manifests and variants of disparate live media output stream manifests. The stream publishing engine 114 may be configured to publish unique-to-client streaming manifests leveraging different indexes created by the indexing and storage system 116 from the various live input streams, pre-encoded media assets, targeted non-programming content and customized programming content based on a defined per-client schedule.

The PEM 115 in the DACIS 103 may be configured to personalize viewer experience of users by communicating with existing content decisioning systems, such as CDS 105, and executing/converting schedules provided, for example from the first programming schedule 111 to the alternate programming schedule 113. The PEM 115 in the DACIS 103 may be further configured to communicate with an ad server, such as the Ad decisioning server 106 a, and stitching in targeted first non-programming content and customized first programming content, as required by the first programming schedule 111 and user preferences. The PEM 115 in the DACIS 103 may be further configured to generate a schedule for a disparate live media output stream of personalized content (i.e., clips or movies), communicating with the stream selection service 142 to switch or failover to different disparate live media input streams, and control overlays and other events triggered via the disparate live media output stream. In accordance with an embodiment, the stream selection service 142 may be used to switch between different output streams when a client device is requesting directly from the stream selection service 142. In accordance with other embodiment, the stream selection service 142 may be used to switch between different streams that may act as inputs for the PEM 115 and/or stream publishing engine 114 to generate a new output stream.

The indexing and storage system 116 in the DACIS 103 may be configured to ingest pre-encoded media assets, advertisement, and (continuously) live stream source manifests, indexes the media content segments, indexes one or more program indicators (such as program boundaries), non-programming indicators (such as ad break locations, overlay opportunities credits, and DRM systems supported, in the repository of schedules, rights, and user preferences database 144.

The per-client disparate live media output streams 117 a, . . . , 117 n may correspond to disparate live media output stream comprising live input streams and/or pre-encoded media assets to be sent back to a client device, upon request, that has been generated from a per-client schedule, such as the first programming schedule 111. Various media container formats of the live input streams and/or pre-encoded media assets may include, but are not limited to, transport stream (TS), fragmented MP4 (fMP4), Common Media Application Format (CMAF) and the like.

The content delivery system 130 may correspond to the network 108, described in FIG. 1. The content delivery system 130 may comprise networks configured for distributing media content to the plurality of client devices 132 a, . . . , 132 n. Generally, the term “content,” “metadata,” “media,” and similar words are used interchangeably to refer to any type of media—audio, videos, datacasts, music, text, images, graphics, articles, still photos, animated photos, moving photos, photo galleries, video galleries, infographics, maps, polls, guest biographies, tweets or other social media, blog posts, and/or the like. The content delivery system 130 may be configured to provide a plurality of disparate live media output streams to the plurality of client devices 132 a, . . . , 132 n (in case packaged content is available on the network 108) or from the content packaging and distribution system 107 (in case packaged content is not available on the network 108). The plurality of disparate live media output streams may be provided to the plurality of client devices 132 a, . . . , 132 n via, for example, a transport stream, a segmented streaming, a progressive download, or any other modes of distributing a multimedia presentation, such as via an over-the-air content delivery/distribution network, a linear content delivery/distribution network, a cable content delivery/distribution network, a satellite content delivery/distribution network, an Internet Protocol (IP) based content delivery/distribution network, and/or the like.

The client devices 132 a, . . . , 132 n may correspond to consumer devices 110 a, . . . , 110 n. In accordance with an embodiment, the client devices 132 a, . . . , 132 n may be content recognition (CR)-enabled devices, such as automatic content recognition enabled devices. The client devices 132 a, . . . , 132 n may be configured to communicate with the Ad decisioning server 106 a, via the content delivery system 130, or a separate communication network.

The stream selection service 142 may comprise suitable logic, circuitry, and interfaces that may be configured to provide a client device, for example, the client device 132 a, requesting to view a disparate live media output stream with a correct variant of disparate live media output stream, based on the geolocation and identification of the client device 132 a, along with data retrieved from the repository of schedules, rights, and user preferences database 144. The stream selection service 142 may further receive user preferences of a user associated with the client device 132 a, for example, to view the recommended/desired existing disparate live media output stream on the client device 132 a. The stream selection service 142 may further store the received preferences in the repository of schedules, rights, and user preferences database 144, and also communicate with the PEM 115. The stream selection service 142 acts as an interface between the PEM 115 of the media packaging and distribution system 102 and the plurality of client devices 132 a, . . . , 132 n.

The repository of schedules, rights, and user preferences database 144 may comprise suitable logic, circuitry, and interfaces that may be configured to execute code to store content rights, user preferences, regional preferences, live schedules, and regional rights. For example, content rights may store availability and platform rights for live input streams in the first programming schedules, such as the first programming schedule 111, the user preferences may store preferences of individual user viewing preferences, the regional preferences may store regional viewing preferences, the live schedules may store the schedules for live input streams, and the regional rights may store regional blackout zones for the various sports leagues, for example. The repository of schedules, rights, and user preferences database 144 may further store data supplied from a stream owner/operator including requirements, preferences, such as pre-defined location-based viewing preferences, stream transition rules, and any required client data, such as service level and zip code.

In operation, in accordance with an aspect (regarding just-in-time insertion of non-programming content and/or programming content) of the disclosure, a media player in a consumer device, such as the consumer device 110 a, may send a first manifest request to the DACIS 103 to receive a disparate live media output stream manifest to begin or continue playback. The first manifest request may comprise one or more parameters, such as universal resource locators and/or identifiers referencing records for one or more live input streams or one or more pre-encoded media assets in the CPDS 107, a plurality of client-specific parameters, and a plurality of client-specified attributes derived from a user interaction with the consumer device, such as the consumer device 110 a. The plurality of client-specific parameters may comprise user preferences and identifiers, client device preferences and identifiers, and one or more rules governed by geolocation data and current position of playback of a first disparate live media output stream at the consumer device, such as the consumer device 110 a. The plurality of client-specified attributes may comprise the user interaction with interactive content in a customized first programming content and a targeted first non-programming content, and a preference for a type and/or category of the targeted first non-programming content and/or the customized first programming content. The user interaction with the interactive content may comprises a selection to exclude the targeted first non-programming content and/or the customized first programming content, a selection to include a subset of the targeted first non-programming content and/or the customized first programming content, and a selection to include all of the targeted first non-programming content and/or the customized first programming content within one or more specified non-programming content locations.

In case the first manifest request is for a first disparate live media output stream, the PEM 115 transmits the one or more parameters in the first manifest request to the stream selection service 142. The stream selection service 142 may determine live input streams and/or pre-encoded media assets, based on the one or more parameters in the first manifest request and in repository of schedules, rights, and user preferences database 144. The stream selection service 142 may transmit the determined identifiers or URLs of the live input streams and/or pre-encoded media assets to the PEM 115. The PEM 115 may then transmit the first manifest request to the CPDS 107 to retrieve metadata for the determined live input streams and/or pre-encoded media assets. The metadata may include, for example ad break locations, overlay markers/triggers, SCTE35 markers, and content duration.

The PEM 115 of the DACIS 103 may further transmit the received first manifest request to the CPDS 107 based on the selected one or more live input streams and/or one or more pre-encoded media assets. The PEM 115 may receive the indexed metadata, for example non-programming indicators, such as ad break locations, graphical treatment indicators, such as overlay markers/triggers, programming indictors, such as SCTE35 markers and content duration, from the CPDS 107.

The PEM 115 may further identify the one or more content placement opportunities defined by the metadata associated with the one or more live input streams and/or one or more pre-encoded media assets. The PEM 115 may further receive additional content, such as targeted first non-programming content from the Ad decisioning server 106 a, and customized first programming content to match one or more personalization parameters from the CDS 105.

The PEM 115 may be configured to generate the first programming schedule 111 for a first client device, such as the client device 132 a, based on selected one or more live input streams and/or the one or more pre-encoded media assets, the associated indexed metadata, and the determined first additional content. The generated first programming schedule 111 may be delivered to the stream publishing engine 114. The stream publishing engine 114 may be configured to select the one or more live input stream manifests and/or the one or more pre-encoded media asset manifests published in the content delivery system 130. The indexing and storage system 116 may be configured to index the plurality of media segments indicated by the one or more pre-encoded media asset manifests and the one or more live input stream manifests, the associated indexed metadata, the targeted first non-programming content, and the customized first programming content may be indexed based on the first programming schedule 111 generated for the first client device, for example the client device 132 a. The stream publishing engine 114 may be further configured to publish the first disparate live media output stream manifest for the first client device, for example the client device 132 a. The DACIS 103 may transmit the published first disparate live media output stream manifest to the media player of the first client device for playback of the first disparate live media output stream, for example the disparate live media output stream 117 a.

In accordance with an embodiment, the PEM 115 may receive a user interaction from the media player of the first client device, for example the client device 132 a. The user interaction may correspond to one of a desired selection corresponding to the user interaction with one or more interactive elements, or a default selection corresponding to a non-interaction of the user with the customized first programming content and/or the targeted first non-programming content in the first disparate live media output stream 117 a played back by the media player. Based on the user interaction with the interactive content, the PEM 115 of the DACIS 103 may be configured to modify the remaining portion of the first programming schedule 111 that generates the first disparate live media output stream 117 a corresponding to the first manifest request generated by the first client device, such as the client device 132 a.

In accordance with another aspect (regarding personalized insertion of playlist of non-programming content and/or programming content) of the disclosure, the DACIS 103 may be configured to receive the first manifest request from the first client device, such as a client device 132 a, to begin or continue playback of a first disparate live media output stream, for example the disparate live media output stream 117 a. In such embodiment, in addition to the plurality of client-specific parameters described above, the plurality of client-specified attributes may comprise a preference for a given type and/or category (or categories) of targeted non-programming content or customized programming content, and a possible time constraint (duration) to fill with content. Thereafter, in similar manner as described above, the PEM 115 may transmit the one or more parameters in the first manifest request to the stream selection service 142. The stream selection service 142 may determine live input streams and/or pre-encoded media assets, based on the one or more parameters in the first manifest request and in repository of schedules, rights, and user preferences database 144. The stream selection service 142 may transmit the determined identifiers or URLs of the live input streams and/or pre-encoded media assets to the PEM 115. The PEM 115 may then transmit the first manifest request to the CPDS 107 to retrieve metadata for the determined live input streams and/or pre-encoded media assets. The metadata may include, for example, categories to which content is assigned to (for example, “basketball”, “sports”, “Knicks”), in addition to ad break locations, overlay markers/triggers, SCTE35 markers, and content duration.

The PEM 115 may identify one or more content placement opportunities defined by the metadata and may transmit a request to the CDS 105 to determine the customized first programming content from the CPDS 107 for matching one or more personalization parameters. Accordingly, the PEM 115 may generate the first programming schedule 111 defining locations and types of one or more decision points defined by the one or more content placement opportunities in the indexed metadata. The one or more decision points may define personalized content preferences, skipping of personalized content and moving to default content, and approval or disapproval of the personalized content. The remaining operations may be similar to the just-in-time insertion of non-programming content and/or programming content.

In accordance with another aspect (regarding stream failover) of the disclosure, the DACIS 103 may be configured to receive the first manifest request from the first client device, such as a client device 132 a. The first manifest request may comprise one or more parameters, as described above. The PEM 115 may transmit the received first manifest request that comprises the one or more parameters to the stream selection service 142. The stream selection service 142 may determine if the set of criteria associated with the first disparate live media output stream is satisfied. The set of criteria may include accessibility of the first disparate live media output stream, update of the first disparate live media output stream and/or compatibility of the first disparate live media output stream having media and/or a manifest with the first manifest request. The stream selection service 142 may be further configured to determine the one or more live input streams and/or one or more pre-encoded media assets based on the one or more parameters in the first manifest request, and additional parameters retrieved from the repository of schedules, rights, and user preferences database 144. The stream selection service 142 may be further configured to determine the one or more live input streams and/or one or more pre-encoded media assets based on rules provided by a stream owner/operator (such as a regional blackout for the first client device leading to an alternative stream to watch) and user preferences (that exclude certain categories) defined in the repository of schedules, rights, and user preferences database 144.

When the set of criteria associated with the first disparate live media output stream is not satisfied, the stream selection service 142 may select a pre-encoded asset indicated in the first manifest request to continue playback as the first disparate live media output stream. The PEM 115 may receive the universal resource locators and/or identifiers that reference records for the selected one or more live input streams or alternate one or more pre-encoded media assets based on the one or more parameters and additional parameters retrieved from the repository of schedules, rights, and user preferences database 144. The PEM 115 may further transmit the received first manifest request to the CPDS 107 based on the selected one or more live input streams or alternate one or more pre-encoded media assets. The PEM 115 may further receive the alternate metadata for the alternate additional content from the CPDS 107. The metadata may include, for example, Ad break locations, overlay markers/triggers, SCTE35 markers/triggers, content duration, and one or more decision points. The alternate metadata may further include a location to transition from the first additional content to the alternate additional content. Thereafter, a placement of alternate additional content within the first disparate live media output stream manifest may be determined based on the associated indexed metadata and the alternate metadata. The PEM 15 may further generate the alternate programming schedule for the first client device, such as the client device 132 a, based on the alternate additional content and alternate metadata. Accordingly, the stream selection service 142 may publish the final disparate live output stream manifest for the first client device, such as the client device 132 a, based on the generated alternate programming schedule.

In accordance with another aspect (regarding server-side dynamic insertion of programming content in an indexed disparate live media output stream) of the disclosure, the PEM 115 may be configured to publish the first programming schedule 111 that may comprises one or more functionalities enabled via one or more constraints and rights associated with at least the first disparate live media output stream. The PEM 115 may publish the first programming schedule 111 referencing at least one live input stream or a pre-encoded asset as a source to be used in at least the first disparate live media output stream. In accordance with an embodiment, the one or more live input streams may comprise pre-encoded media assets. In accordance with another embodiment, the one or more live input streams may comprise singularly encoded live input streams. In accordance with an embodiment, the one or more functionalities enabled via the one or more constraints and rights may include a first functionality to restart a programming content in the first disparate live media output stream that is presented on at least the first client device, such as the client device 132 a. In accordance with another embodiment, the one or more functionalities enabled via the one or more constraints and rights may include a second functionality to skip to a future scheduled programming content in the first disparate live media output stream. In accordance with another embodiment, the one or more functionalities enabled via the one or more constraints and rights may include a third functionality to time-shift within the programming content in the first disparate live media output stream. In accordance with another embodiment, the one or more functionalities enabled via the one or more constraints and rights may include a fourth functionality to resume playback within the programming content in the first disparate live media output stream. In accordance with an embodiment, the one or more constraints and rights associated with at least the first disparate live media output stream may be retrieved from the repository of schedules, rights, and user preferences database 144.

In accordance with an embodiment, the indexing and storage system 116 of the DACIS 103 may be configured to receive instructions from the stream publishing engine 114 to begin indexing of the one or more pre-encoded media assets and/or the one or more live input streams referenced in the published first programming schedule 111. The indexing and storage system 116 of the DACIS 103 may be further configured to record content of manifest data that may correspond to one or both of the one or more pre-encoded media assets and/or the one or more live input streams, including any variants defined in a master manifest. The manifest data may define at least an associated media content, one or more programming indicators (such as SCTE messages), timing metadata, one or more media content identifiers, and one or more contextual event identifiers. The timing metadata may correspond to the playback position in the published first programming schedule 111. The indexing and storage system 116 of the DACIS 103 may further process the manifest data to create the indexed metadata. The indexed metadata may define one or more program indicators (such as program start/end) and calculated durations, a program identification (that correspond to a programming content that is currently playing), non-programming content indicators (such as Ad break start/end) and calculated durations, a non-programming content identification (that correspond to Ads that are currently playing), and one or more event markers (such as blackout notifications). In accordance with an embodiment, the indexing and storage system 116 of the DACIS 103 may be configured to maintain the manifest data and the indexed metadata to encompass a time-range specified in the published first programming schedule 111.

In accordance with an embodiment, the stream publishing engine 114 may be configured to generate the indexed first disparate live media output stream for the first client device, such as the client device 132 a, based on the published first programming schedule 111. In accordance with an embodiment, the content delivery system 130 of the DACIS 103 may be configured to present the generated indexed first disparate live media output stream on the first client device, such as the client device 132 a.

In accordance with an embodiment, the stream publishing engine 114 may be configured to receive a client request from the first client device, such as the client device 132 a, based on the playback of the indexed first disparate live media output stream at the first client device, such as the client device 132 a. The client request may comprise at least a program identifier referenced in the published first programming schedule 111 with respect to the playback position in the published first programming schedule 111. The programming identifier may be associated with a programming content that may be selected based on a user input provided at the first client device, such as the client device 132 a. Examples of the user input may include, but not limited to, a selection of the programming content from a list of programming content or a selection of a restart or resume option to initiate corresponding operation at the DACIS 103 operation. The client request may be generated by the first client device, such as the client device 132 a, based on the user input while the first disparate live media output stream (returned from the DACIS 103) is played back at the first client device, such as the client device 132 a.

Based on the user input, the first client device, such as the client device 132 a, may instruct the DACIS 103 to perform an operation, such as restart, skip, time-shift, or resume, in accordance with one or more functionalities enabled via the one or more constraints and rights associated with at least the first disparate live media output stream.

In accordance with an embodiment, when the one or more functionalities correspond to the first functionality to restart the programming content in the first disparate live media output stream, at least the first client device, such as the client device 132 a, may be configured to determine the program identifier of a programming content that is currently or recently played back in the first disparate live media output stream. The program identifier of the programming content may be determined based on a request for a list of programming content, via for example an electronic program guide, associated with the first disparate live media output stream from the repository of schedules, rights, and user preferences database 144.

As the first client device, such as the client device 132 a, plays the first disparate live media output stream returned from the DACIS 103, the user input may be provided to restart the programming content that is currently or recently played back in the first disparate live media output stream, in accordance with the first functionality defined in the published first programming schedule 111. Based on the user input, the stream publishing engine 114 in the DACIS 103 may be configured to receive the client request from the first client device, such as the client device 132 a. The client request thus received, includes the program identifier for the programming content (that is currently or recently played back in the first disparate live media output stream in accordance with the first functionality defined in the published first programming schedule 111) to be restarted.

The stream publishing engine 114 may query the indexing and storage system 116 with the received program identifier. The indexing and storage system 116 may provide the manifest data and indexed metadata of the programming content associated with the program identifier back to the stream publishing engine 114. The stream publishing engine 114 may validate against the published first programming schedule 111 that the programming content is eligible for a restart. If the programming content is found to be ineligible for the restart, the stream publishing engine 114 may ignore the client request and continue with the playback of the first disparate live media output stream. However, the programming content is found to be eligible for the restart, the stream publishing engine 114 may insert the manifest data and indexed metadata of the programming content associated with the program identifier to the first disparate live media output stream manifest in accordance with the first functionality. Accordingly, the stream publishing engine 114 may alter the first disparate live media output stream, based on the insertion of the manifest data and indexed metadata associated with the program identifier referenced in the first programming schedule 111. Such an altered first disparate live media output stream may comprise the manifest data, the indexed metadata and an updated playback position. Thus, the stream publishing engine 114 may alter the first disparate live media output stream to start playing out the programming content, as specified by the program identifier from the starting point.

In accordance with another embodiment, the one or more functionalities correspond to the second functionality to skip to a future scheduled programming content in the first disparate live media output stream. In such an embodiment, the second functionality is allowed for a first set of pre-encoded media content or the live input stream that comprises a second set of pre-encoded media content. As the first client device, such as the client device 132 a, plays the first disparate live media output stream returned from the DACIS 103, the user input may be provided to select a future scheduled programming content from a list of programming content (that corresponds to upcoming programming content), in accordance with the second functionality defined in the published first programming schedule 111. In such an embodiment, at least the first client device, such as the client device 132 a, may be configured to determine the program identifier based on selection of the future scheduled programming content from the list of programming content associated with the first disparate live media output stream from the repository of schedules, rights, and user preferences database 144. Based on the user input, the stream publishing engine 114 may receive the client request from the first client device, such as the client device 132 a, to start the selected future scheduled programming content, in accordance with the second functionality defined in the published first programming schedule 111. The client request thus received, includes the program identifier for the future scheduled programming content to be skipped to and get started with.

The stream publishing engine 114 in the DACIS 103 may query the indexing and storage system 116 with the received program identifier. The indexing and storage system 116 may provide the manifest data and indexed metadata of the programming content associated with the program identifier back to the stream publishing engine 114. The stream publishing engine 114 may validate against the published first programming schedule 111 that the selected future scheduled programming content is eligible for a playback at a time of the client request. If the eligibility of the selected future scheduled programming content is determined to be invalid, the stream publishing engine 114 in the DACIS 103 may ignore the client request and the playback of the first disparate live media output stream is continued at the first client device, such as the client device 132 a, as per the published first programming schedule 111. If the eligibility of the selected future scheduled programming content is determined to be valid, the stream publishing engine 114 may insert the manifest data and indexed metadata of the programming content associated with the program identifier to the first disparate live media output stream manifest in accordance with the second functionality. Accordingly, the stream publishing engine 114 may alter the first disparate live media output stream, based on the insertion of the manifest data and indexed metadata associated with the program identifier referenced in the first programming schedule 111. Such an altered first disparate live media output stream may comprise the manifest data, the indexed metadata and an updated playback position. Thus, the stream publishing engine 114 may play out the selected future scheduled programming content associated with the program identifier in the manifest data, the indexed metadata and the updated playback position, corresponding to a starting point of the selected future scheduled programming, of the altered first disparate live media output stream.

In accordance with another embodiment, the one or more functionalities include the third functionality to time-shift within the programming content in the first disparate live media output stream. In such an embodiment, the first disparate live media output stream manifest associated with the first disparate live media output stream presented at the client interface of the first client device, such as the client device 132 a, comprises timing metadata. The timing metadata may comprise embedded time-based identifiers corresponding to media segments in the first disparate live media output stream.

The program identifier of the programming content may be determined based on a request for a list of programming content, via for example an electronic program guide, associated with the first disparate live media output stream from the repository of schedules, rights, and user preferences database 144. The list of programming content may comprise additional metadata that may control the third functionality which corresponds to each programming content as enabled via the one or more constraints and rights in the published first programming schedule 111.

In accordance with an embodiment, the client interface may be presented at the first client device, such as the client device 132 a, in accordance with the third functionality. Accordingly, a seeking option within the programming content in the first disparate live media output stream may be enabled at the client interface of at least the first client device, such as the client device 132 a. The seeking option may be enabled in accordance with a default playback buffer of at least the first client device, such as the client device 132 a, when the programming content that is currently played back does not allow for the third functionality. In accordance with another embodiment, a seeking option within each programming content in the first disparate live media output stream may be enabled at the client interface of at least the first client device, such as the client device 132 a, when the programming content that is currently played back allows for the third functionality. The seeking operation forwards in time may be enabled up to a latest published media segment within the first disparate live media output stream manifest. In accordance with another embodiment, the seeking option, such as a seeking operation backwards in time, is enabled within each programming content. The seeking operation backwards in time continues into a prior programming content when the seeking operation backwards in time reaches a starting point of the programming content that is currently played back and the third functionality of the prior programming content is enabled.

As the first client device, such as the client device 132 a, plays the first disparate live media output stream returned from the DACIS 103, the user input may be provided to select one of the above seeking options, such as the seeking operation forwards in time or the seeking operation backwards in time, in accordance with the third functionality defined in the published first programming schedule 111.

Based on the user input, the stream publishing engine 114 may receive the client request from the first client device, such as the client device 132 a, to time-shift within the programming content in the first disparate live media output stream, in accordance with the third functionality. The client request thus received, includes the program identifier for the programming content (within which the time-shift is to be performed) and a seeking position to which playback is to be time-shifted to. The stream publishing engine 114 may query the indexing and storage system 116 with the received program identifier and the seeking position to which playback is to be time-shifted to. The indexing and storage system 116 may determine the manifest data and indexed metadata corresponding to the programming content, corresponding to the first programming schedule 111, in proximity to the seeking position for the seeking operation and returns to the stream publishing engine 114. The stream publishing engine 114 may insert the determined manifest data and indexed metadata of the programming content associated with the program identifier to the first disparate live media output stream manifest in accordance with the third functionality. The stream publishing engine 114 may alter the first disparate live media output stream, based on the insertion of the determined manifest data and indexed metadata associated with the program identifier referenced in the first programming schedule 111. Such an altered first disparate live media output stream may comprise the manifest data, the indexed metadata and an updated playback position. The stream publishing engine 114 may play out the programming content associated with the program identifier in the manifest data, the indexed metadata and the updated playback position, of the altered first disparate live media output stream. The altered first disparate live media output stream may be viewed at the first client device, such as the client device 132 a.

In accordance with another embodiment, the one or more functionalities include the fourth functionality to resume playback within the programming content in the first disparate live media output stream. In such an embodiment, the first disparate live media output stream manifest associated with the first disparate live media output stream comprises timing metadata. The timing metadata may comprise embedded time-based identifiers corresponding to media segments in the first disparate live media output stream. In accordance with an embodiment, the client interface may be presented at the first client device, such as the client device 132 a, in accordance with the fourth functionality which corresponds to each programming content as enabled via the one or more constraints and rights. The first client device, such as the client device 132 a, may proceed to playback the first disparate live media output stream. As the playback occurs, the first client device, such as the client device 132 a, remains updated about the current playback time as provided by the embedded time-based identifiers in the timing metadata corresponding to media segments in the first disparate live media output stream. As the first disparate live media output stream is played back at the first client device, such as the client device 132 a, a user input may be provided, which may correspond to a pause operation or a termination operation of the playback of the first disparate live media output stream at the first client device, such as the client device 132 a.

Based on the pause operation or a termination operation, a stream identifier of the first disparate live media output stream, the program identifier of the programming content that is currently playing back, and the timing metadata within the first disparate live media output stream may be captured by at least the first client device, such as the client device 132 a. In accordance with an embodiment, the stream publishing engine 114 may be configured to receive the client request from the first client device, such as the client device 132 a, or the second client device, such as the client device 132 b, to resume playback of the first disparate live media output stream on at least one of the first client device, such as the client device 132 a, or the second client device, such as the client device 132 b. The stream publishing engine 114 in the DACIS 103 may be further configured to check that if programming content that is currently played back does not allow for the fourth functionality, proceed with playout of the programming content from live point. Else, the stream publishing engine 114 in the DACIS 103 may be configured to determine the first programming schedule 111 from the set of programming schedules associated with the stream identifier from the indexing and storage system 116 based on the timing metadata in the client request.

In accordance with an embodiment, for an altered schedule, the stream publishing engine 114 in the DACIS 103 may be configured to determine an alternate representation of the first disparate live media output stream based on the repository of schedules, rights, and user preferences database 144 or third-party systems. The stream publishing engine 114 in the DACIS 103 may be further configured to reconstruct the first disparate live media output stream for an altered schedule associated with the stream identifier, the program identifier, and the timing metadata, and generate a second disparate live media output stream based on the insertion of the manifest data and indexed metadata of the programming content associated with the program identifier referenced in altered schedule, in addition to stream identifier and timing metadata. The programming content associated with the program identifier in the manifest data, indexed metadata and updated playback position, of the second disparate live media output stream may then be played out by the stream publishing engine 114.

In accordance with another embodiment, for an unaltered schedule, the stream publishing engine 114 in the DACIS 103 may be configured to insert the manifest data and the indexed metadata of the programming content associated with the program identifier to the first disparate live media output stream manifest in accordance with the fourth functionality. The stream publishing engine 114 may be further configured to generate the second disparate live media output stream, based on the insertion of the determined manifest data and indexed metadata associated with the program identifier referenced in the first programming schedule 111, in addition to the stream identifier and the timing metadata. Such a generated second disparate live media output stream may comprise the manifest data, the indexed metadata, and the updated playback position for resuming at one or both of the first client device, such as the client device 132 a, and the second client device, such as client device 132 b, as requested. Accordingly, the stream publishing engine 114 may be configured to play out the programming content associated with the program identifier in the manifest data, the indexed metadata and the updated playback position, of the second disparate live media output stream.

FIG. 2 illustrates segmentation of live input streams and pre-encoded media assets for the first programming schedule 111 or the alternate programming schedule 113 for publishing a disparate per-client live media output stream based on dynamic insertion of targeted non-programming content and customized programming content by the DACIS 103 of FIG. 1B, and for server-side dynamic insertion of programming content in an indexed disparate live media output stream, in accordance with exemplary embodiments of the disclosure. Referring to the exemplary arrangement of FIG. 2, there is shown a first live input stream 202, a first pre-encoded media asset 204, and a second live input stream 206. There is also shown a targeted first non-programming content 208 placed after the first live input stream 202, and a customized first programming content 210 placed after the first pre-encoded media asset 204. The first live input stream 202 may be segmented into a first set of video segments 202 a, 202 b, 202 c, . . . , 202 n. Similarly, the first pre-encoded media asset 204 and the second live input stream 206 may also be segmented into second set of video segments 204 a, 204 b, 204 c, . . . , 204 n, and third set of video segments 206 a, 206 b, 206 c, . . . , 206 n respectively. By way of example, the segmentation may be executed by a segmenting system (for example a live stream encoder/packager and/or a content encoder/packager (not shown)) during a preparation stage of the media assets. The encode stage may create various quality levels and the package stage segments the content into the short segments, and produces the correct format, such as TS, fMP4, or CMAF and encrypts the media content to prevent piracy. In accordance with an embodiment, the segments of the first set of video segments 202 a, 202 b, 202 c, . . . , 202 n, the second set of video segments 204 a, 204 b, 204 c, . . . , 204 n, and third set of video segments 206 a, 206 b, 206 c, . . . , 206 n, may be segmented into consistent length, for example, 10 seconds segments. It may be advantageous to have a consistent and smaller file size of segments to be able to quickly push to the content delivery system 130, and also for quick downloading by a media player at the end-user side, such as on the plurality of consumer devices 110 a, . . . , 110 n.

It should be understood by those skilled in the art that various changes may be made and segments of different file sizes (or length) may be used without departure from the scope of the present disclosure. Further, other streaming protocols may require a different processing of media content. Thus, the scope of the disclosure should not be limited to the processing or preparation of media content to allow delivery using different delivery methods, streaming protocols, or distribution system, known in the art. Further, instead of the live input streams and pre-encoded media asset arranged, as shown, different arrangements per the first programming schedule 111 or the alternate programming schedule 113 may be possible with respect to interstitial content items, such as the targeted first non-programming content 208 and the customized first programming content 210.

The insertion of the live input stream manifests, pre-encoded media asset manifests, the targeted first non-programming content 208 and the customized first programming content 210 may be done on-the-fly based on dynamic scheduling by the PEM 115 that generates the first programming schedule 111 or the alternate programming schedule 113. The insertion may be driven by real time or near-real time content context analysis, user-selection on the consumer devices 110 a, . . . , 110 n, or driven by external data received from the external data source 120. The PEM 115 in association with the stream selection service 142 may be configured to insert live input streams, such as the first live input stream 202 and the second live input stream 206, or pre-stored media assets, such as the first pre-encoded media asset 204, the targeted first non-programming content 208 and the customized first programming content 210, in an existing disparate live media output stream based on manipulation of a manifest the existing disparate live media output stream, such as an existing channel.

In accordance with an embodiment, each segment of the first set of video segments 202 a, 202 b, 202 c, . . . , 202 n, the second set of video segments 204 a, 204 b, 204 c, . . . , 204 n, and third set of video segments 206 a, 206 b, 206 c, . . . , 206 n, may be further processed to be stored at various quality levels, and content encryption modes for the purposes of adaptive bitrate streaming and digital rights management, for example, the video segment 202 a may be stored in a plurality of quality levels, for example, high definition (HD), high dynamic range (HDR) video, or different quality levels in accordance with specified pixel resolutions, bitrates, frame rates, and/or sample frequencies. As each of the media content, such as 202 to 206, are encoded, segmented, and stored with the plurality of quality levels in a media content master storage system. The media content may be re-used to create new channels, such as a new disparate live media output stream, without having to re-encode a selected live input stream or a pre-encoded media asset when a new disparate live media output stream is created using the live input streams or a pre-encoded media asset.

For the sake of brevity, and with reference to FIG. 2, there is shown an example of publishing the first or the updated (or alternate) disparate live media output streams based on dynamic insertion of targeted non-programming content and customized programming content by the DACIS 103 of FIG. 1B. It is to be understood that media packaging for different delivery methods (such as analog terrestrial broadcast, digital terrestrial broadcast, direct-to-home satellite broadcast, cable, other Internet Protocol (IP)-based delivery methods, over-the-top television (OTT)), different streaming protocols, or distribution system, may be different. The media content may be prepared to be viewed one or more of the plurality of consumer devices 110 a, . . . , 110 n, based on at least the desired delivery method, delivery conditions, content protection requirements, to satisfy operational and technical requirements, as needed. The operational and technical requirements may include, but are not limited to, media encoding, media segmentation, programming schedule (or manifest) creation or manipulation requirements, desired media encryption, and/or metadata signaling requirements. For example, in certain scenarios and for certain media content delivery methods, network bandwidth, network conditions, or device-type where media content is to be consumed may not be variable or known in advance. In such a case, creating different quality levels for same media content may not be required. Further, based on different operational and technical requirements, publishing of disparate live media output stream may be different. The media content that is prepared and distributed may include both the programming content, such as long-form presentations, short-form presentations, news or sporting events; and non-programming content, such as paid advertisements, public service advertisements, or promotional material.

FIG. 3 illustrates an exemplary scenario associated with publishing a disparate live media output stream by the DACIS 103 of FIG. 1B, in accordance with an exemplary embodiment of the disclosure. Referring to the exemplary scenario 300, there are illustrated two disparate live media output streams 302 and 304 published for two users associated with the client devices 132 a and 132 n, respectively. The disparate live media output stream 302 may be existing disparate live media output stream for the client device 132 a. The disparate live media output stream 304 may be a disparate per-client live media output stream published based on dynamic insertion of targeted non-programming content and customized programming content by the DACIS 103 of FIG. 1B for the client device 132 n.

The live NBA game may be scheduled to start at 8:00 pm. However, a user associated with the client device 132 n tunes in early to watch the NBA game, for example at 7:15 pm. However, the user may not be interested in watching the end of the current programming media content. In such a case, the PEM 115 in the DACIS 103 may determine targeted non-programming content, such as sports items ads, and customized programming content, such as NBA highlights of previous game and generates the alternate programming schedule 113. Accordingly, the stream publishing engine 114 in the DACIS 103 may publish an alternate disparate live media output stream 117 n for the client device 132 n. At 8:00 pm, the DACIS 103 may switch back to the live NBA game scheduled at 8:00 pm.

FIG. 3A illustrates an exemplary disparate live media output stream manifest, in accordance with an exemplary embodiment of the disclosure. Referring to an exemplary scenario 300A, there is illustrated a disparate live media output stream manifest 302 published for a user associated with the first client device, such as client device 132 a. There are shown indexed media segments corresponding to four different programming content P1, P2, P3 and P4, with program start markers PS1, PS2, PS3, and PS4, respectively, scheduled as per the first programming schedule 111. Each of the programming content P1, P2, P3 and P4, is shown to comprise five indexed segments. In accordance with the exemplary embodiment, there is shown the program start marker PS2 corresponding to the program start/restart identifier associated with the second programming content P2, which is the currently playing programming content. There are further shown a live point LP that corresponds to the current playback position in the published first programming schedule, a live edge LE that corresponds to the trailing edge of the live window, a join point JP that corresponds to a point when the user associated with the client device 132 a joins to view the disparate live media output stream 302.

In accordance with a first use case corresponding to the first functionality to restart programming content, such as the programming content P2, in a disparate live media output stream, the user may provide a user input at the client device 132 a to restart the programming content P2 that is currently being played back. The current playback position as per the published first programming schedule 111 corresponds to the live point LP. The DACIS 103 may be configured to insert the manifest data and indexed metadata of the second programming content P2 associated with the program identifier (of the programming content P2) to the disparate live media output stream manifest 302 and generate a corresponding altered disparate live media output stream that comprises the manifest data, the indexed metadata and an updated playback position. The updated playback position as per the published first programming schedule 111 corresponds to the program start marker PS2.

In accordance with a second use case corresponding to the second functionality to skip to a future scheduled programming content, such as the programming content P4, in the disparate live media output stream, the user may provide a user input at the client device 132 a to skip to the programming content P4 from the live point LP corresponding to the programming content P2 (that is currently being played back). The DACIS 103 may be configured to insert the manifest data and indexed metadata of the fourth programming content P4 associated with the program identifier (of the programming content P4) to the disparate live media output stream manifest 302 and generate a corresponding altered disparate live media output stream that comprises the manifest data, the indexed metadata and an updated playback position. The updated playback position as per the published first programming schedule 111 corresponds to the program start marker PS4 of the programming content P4. In such case, the media segments of the programming content P4 may correspond to a pre-encoded media asset converted to a live stream.

In accordance with a third use case corresponding to the third functionality to time-shift within a programming content, such as the programming content P1, in the disparate live media output stream, the user may provide a user input at the client device 132 a to time-shift to the programming content P1 from the live point LP corresponding to the programming content P2 (that is currently being played back). The DACIS 103 may be configured to insert the manifest data and indexed metadata of the programming content P1 associated with the program identifier (of the programming content P1) and seeking point SP to the disparate live media output stream manifest 302 and generate a corresponding altered disparate live media output stream that comprises the manifest data, the indexed metadata and an updated playback position. The updated playback position as per the published first programming schedule 111 corresponds to the seeking point SP of the programming content P1.

In accordance with a fourth use case corresponding to the fourth functionality to resume playback within the programming content, such as the programming content P2, in the disparate live media output stream, the user may provide a user input at the client device 132 a to resume playback of the programming content P2 from the live point LP at the other client device 132 b. The DACIS 103 may be configured to reconstruct the disparate live media output stream manifest based on the stream identifier, the program identifier, and the timing metadata (corresponding to the live point LP). The user then switches to the client device 132 b and playback is resumed using the state (saved by the client device 132 a corresponding to the stream identifier, the program identifier, and the timing metadata) from the live point LP.

FIGS. 4A to 4D depict flowcharts illustrating exemplary operations for publishing a disparate per-client live media output stream based on dynamic insertion of targeted non-programming content and customized programming content in the media packaging and distribution system 102 of FIG. 1B, in accordance with an exemplary embodiment of the disclosure.

At 602, a first programming schedule that comprises one or more functionalities enabled via one or more constraints and rights associated with at least a first disparate live media output stream, may be published. In accordance with an embodiment, the PEM 115 of the DACIS 103 may be configured to publish the first programming schedule 111 that comprises one or more functionalities enabled via one or more constraints and rights associated with at least the first disparate live media output stream.

In accordance with an embodiment, the published first programming schedule 111 may reference one or more pre-encoded media assets and/or one or more live input streams for at least the first disparate live media output stream. Thus, the PEM 115 of the DACIS 103 may publish the first programming schedule 111 referencing at least one live input stream or a pre-encoded asset as a source to be used in at least the first disparate live media output stream. In accordance with an embodiment, the one or more live input streams may comprise pre-encoded media assets. In accordance with another embodiment, the one or more live input streams may comprise singularly encoded live input streams. Various media container formats of the live input streams and/or pre-encoded media assets may include, but are not limited to, transport stream (TS), fragmented MP4 (fMP4), Common Media Application Format (CMAF) and the like.

As discussed above, the first programming schedule 111 may indicate the one or more functionalities enabled via the one or more constraints and rights associated with at least the first disparate live media output stream. In accordance with an embodiment, the one or more functionalities enabled via the one or more constraints and rights may include a first functionality to restart a programming content in the first disparate live media output stream that is presented on at least the first client device, such as the client device 132 a. In accordance with another embodiment, the one or more functionalities enabled via the one or more constraints and rights may include a second functionality to skip to a future scheduled programming content in the first disparate live media output stream. In accordance with another embodiment, the one or more functionalities enabled via the one or more constraints and rights may include a third functionality to time-shift within the programming content in the first disparate live media output stream. In accordance with another embodiment, the one or more functionalities enabled via the one or more constraints and rights may include and a fourth functionality to resume playback within the programming content in the first disparate live media output stream.

In accordance with an embodiment, the one or more constraints and rights associated with at least the first disparate live media output stream may be retrieved from the repository of schedules, rights, and user preferences database 144. The repository of schedules, rights, and user preferences database 144 may be configured to store the one or more constraints and rights associated with disparate live media output streams that may be derived from one or more of schedules for all source feeds, availability rights for all the content in the schedules, regional blackout zones for the various sports leagues, predefined location-based viewing preferences, individual client viewing preferences, and any viewing rules, transition rules, and business rules provided by or applicable to the stream owner operator.

At 604, the one or more pre-encoded media assets and/or the one or more live input streams referenced in the published first programming schedule 111 may be indexed. In accordance with an embodiment, the indexing and storage system 116 of the DACIS 103 may be configured to index the one or more pre-encoded media assets and/or the one or more live input streams.

At 604A, instructions from the stream publishing engine 114 to begin indexing of the one or more pre-encoded media assets and/or the one or more live input streams referenced in the published first programming schedule 111 may be received. In accordance with an embodiment, the indexing and storage system 116 of the DACIS 103 may be configured to receive instructions from the stream publishing engine 114 to begin indexing of the one or more pre-encoded media assets and/or the one or more live input streams referenced in the published first programming schedule 111. The indexing and storage system 116 of the DACIS 103 may be configured to fetch one or more pre-encoded media assets and/or the one or more live input streams referenced in the published first programming schedule 111 from the CPDS 107. In accordance with an embodiment, the indexing and storage system 116 of the DACIS 103 may be configured to index the one or more live input streams repeatedly at variable time intervals.

In accordance with an embodiment, the indexing and storage system 116 of the DACIS 103 may be further configured to record content of manifest data that may correspond to one or both of the one or more pre-encoded media assets and/or the one or more live input streams, including any variants defined in a master manifest. The manifest data may correspond to one or both of an encoded live input stream and a pre-encoded media asset associated with the program identifier. The manifest data may define at least an associated media content, one or more programming indicators (such as SCTE messages), timing metadata, one or more media content identifiers, and one or more contextual event identifiers. The timing metadata may correspond to the playback position in the published first programming schedule 111.

At 604B, the manifest data may be processed to create the indexed metadata. In accordance with an embodiment, the indexing and storage system 116 of the DACIS 103 may be further configured to process the manifest data to create the indexed metadata. The indexed metadata may define one or more program indicators (such as program start/end) and calculated durations, a program identification (that correspond to a programming content that is currently playing), non-programming content indicators (such as Ad break start/end) and calculated durations, a non-programming content identification (that correspond to Ads that are currently playing), and one or more event markers (such as blackout notifications).

At 604C, the manifest data and the indexed metadata may be maintained to encompass a time-range specified in the published first programming schedule 111. In accordance with an embodiment, the indexing and storage system 116 of the DACIS 103 may be further configured to maintain the manifest data and the indexed metadata to encompass a time-range specified in the published first programming schedule 111. For example, the indexing and storage system 116 may keep 24 hours of indexed metadata despite the live input stream being published in 5 minute increments.

At 606, the indexed first disparate live media output stream for the first client device may be generated based on the published first programming schedule 111. In accordance with an embodiment, the stream publishing engine 114 of the DACIS 103 may be configured to generate the indexed first disparate live media output stream for the first client device, such as the client device 132 a, based on the published first programming schedule 111. The stream publishing engine 114 may be configured to publish unique-to-client streaming manifests leveraging different indexes created by the indexing and storage system 116 from the various live input streams, pre-encoded media assets, targeted non-programming content and customized programming content based on a defined per-client schedule, such as the published first programming schedule 111. In other words, the stream publishing engine 114 of the DACIS 103 may be configured to generate the indexed first disparate live media output stream for the first client device, such as the client device 132 a, based on the indexed one or more pre-encoded media assets and/or one or more live input streams, as the published first programming schedule 111 now references indexed one or more pre-encoded media assets and/or the one or more live input streams.

At 608, the generated indexed first disparate live media output stream for the first client device, such as the client device 132 a, may be presented on the first client device, such as the client device 132 a. In accordance with an embodiment, the content delivery system 130 of the DACIS 103 may be configured to present the generated indexed first disparate live media output stream on the first client device, such as the client device 132 a. The indexed first disparate live media output stream may be provided to the first client device, such as the client device 132 a, via, for example, a transport stream, a segmented streaming, a progressive download, or any other modes of distributing a multimedia presentation, such as via an over-the-air content delivery/distribution network, a linear content delivery/distribution network, a cable content delivery/distribution network, a satellite content delivery/distribution network, an Internet Protocol (IP) based content delivery/distribution network, and/or the like.

At 610, a client request may be received from the first client device, such as the client device 132 a, based on a playback of the indexed first disparate live media output stream at the first client device, such as the client device 132 a. In accordance with an embodiment, the stream publishing engine 114 in the DACIS 103 may be configured to receive the client request from the first client device, such as the client device 132 a, based on the playback of the indexed first disparate live media output stream at the first client device, such as the client device 132 a.

The client request may comprise at least the program identifier referenced in the published first programming schedule 111 with respect to the playback position in the published first programming schedule 111. In accordance with an embodiment, the playback position may be an indicator of a current play position within a media item of the first disparate live media output stream. For example, the playback position may be a displayed icon at the first client device, such as the client device 132 a, or a line that indicates a relative position of playback within some other indicia (e.g., a displayed bar) of the total play time of the media item.

In accordance with an embodiment, the program identifier may be specified within the first disparate live media output stream manifest that corresponds to the first disparate live media output stream for a specific programming content, for example a programming content that is currently or recently played back. Such programming content may include one or more media segments corresponding to at least an encoded live input stream and a pre-encoded media asset within a playout buffer of the first disparate live media output stream manifest. The programming identifier may be associated with a programming content that may be selected based on a user input provided at the first client device, such as the client device 132 a. Examples of the user input may include, but not limited to, a selection of the programming content from a list of programming content or a selection of a restart or resume option to initiate corresponding operation at the DACIS 103 operation.

The client request may be generated by the first client device, such as the client device 132 a, based on the user input while the first disparate live media output stream (returned from the DACIS 103) is played back at the first client device, such as the client device 132 a. Based on the user input, the first client device, such as the client device 132 a, may instruct the DACIS 103 to perform an operation, such as restart, skip, time-shift, or resume, in accordance with one or more functionalities enabled via the one or more constraints and rights associated with at least the first disparate live media output stream. In accordance with various embodiments, the one or more functionalities may include the first functionality to restart a programming content in the first disparate live media output stream that is presented on at least the first client device, such as the client device 132 a, the second functionality to skip to a future scheduled programming content in the first disparate live media output stream, the third functionality to time-shift within the programming content in the first disparate live media output stream, and the fourth functionality to resume playback within the programming content in the first disparate live media output stream.

In accordance with an embodiment, when the one or more functionalities correspond to the first functionality to restart the programming content in the first disparate live media output stream, control passes to step 612 in the flowchart 600B. In such an embodiment, at least the first client device, such as the client device 132 a, may be configured to determine the program identifier of a programming content that is currently or recently played back in the first disparate live media output stream. The program identifier of the programming content may be determined based on a request for a list of programming content, via for example an electronic program guide, associated with the first disparate live media output stream from the repository of schedules, rights, and user preferences database 144. The list of programming content may comprise additional metadata that may control the first functionality of a current programming content and each of past programming content as enabled via the one or more constraints and rights in the published first programming schedule 111.

In accordance with another embodiment, the program identifier of the programming content may be specified within the first disparate live media output stream manifest. The first disparate live media output stream manifest corresponds to the first disparate live media output stream for the programming content that is currently or recently played back and still within the live window of the published first disparate live media output stream manifest, as shown in FIG. 3A.

As the first client device, such as the client device 132 a, plays the first disparate live media output stream returned from the DACIS 103, the user input may be provided to restart the programming content that is currently or recently played back in the first disparate live media output stream, in accordance with the first functionality defined in the published first programming schedule 111.

Based on the user input, the stream publishing engine 114 in the DACIS 103 may be configured to receive the client request from the first client device, such as the client device 132 a. The client request thus received, includes the program identifier for the programming content (that is currently or recently played back in the first disparate live media output stream in accordance with the first functionality defined in the published first programming schedule 111) to be restarted.

At 612, the indexing and storage system 116 may be queried with the received program identifier. In accordance with an embodiment, the stream publishing engine 114 in the DACIS 103 may be configured to query the indexing and storage system 116 with the received program identifier. The stream publishing engine 114 in the DACIS 103 may query the indexing and storage system 116 for an appropriate manifest data and indexed metadata of the programming content associated with the program identifier.

At 614, manifest data and indexed metadata of the programming content associated with the program identifier may be provided back to the stream publishing engine 114. In accordance with an embodiment, the indexing and storage system 116 in the DACIS 103 may be configured to provide the manifest data and indexed metadata of the programming content associated with the program identifier back to the stream publishing engine 114. As discussed above, the manifest data may define at least an associated media content, one or more programming indicators (such as SCTE messages), timing metadata, one or more media content identifiers, and one or more contextual event identifiers. The timing metadata may correspond to the playback position in the published first programming schedule 111.

At 616, it may be determined whether the eligibility of the programming content is valid against the published first programming schedule 111 for the restart. In accordance with an embodiment, the stream publishing engine 114 in the DACIS 103 may be further configured to validate against the published first programming schedule 111 that the programming content is eligible for a restart. In accordance with an embodiment, the eligibility of the programming content is determined to be invalid against the published first programming schedule 111 for the restart, and the control passes to 620. In accordance with another embodiment, the eligibility of the programming content is determined to be valid against the published first programming schedule 111 for the restart, and the control passes to 622.

At 618, the client request may be ignored and playback of the first disparate live media output stream is continued at the first client device, such as the client device 132 a, as per the published first programming schedule 111, when the eligibility of the programming content is determined to be invalid against the published first programming schedule 111 for the restart. In accordance with an embodiment, the stream publishing engine 114 in the DACIS 103 may be configured to ignore the client request and the playback of the first disparate live media output stream is continued at the first client device, such as the client device 132 a, as per the published first programming schedule 111, when the eligibility of the programming content is determined to be invalid against the published first programming schedule 111 for the restart.

At 620, the manifest data and indexed metadata of the programming content associated with the program identifier may be inserted to the first disparate live media output stream manifest in accordance with the first functionality, when the programming content is eligible for the restart. In accordance with an embodiment, the stream publishing engine 114 in the DACIS 103 may be configured to insert the manifest data and indexed metadata of the programming content associated with the program identifier to the first disparate live media output stream manifest in accordance with the first functionality, when the programming content is eligible for the restart.

At 620A, the first disparate live media output stream may be altered based on the insertion of the manifest data and indexed metadata associated with the program identifier referenced in the first programming schedule 111. In accordance with an embodiment, the stream publishing engine 114 in the DACIS 103 may be configured to alter the first disparate live media output stream, based on the insertion of the manifest data and indexed metadata associated with the program identifier referenced in the first programming schedule 111. Such an altered first disparate live media output stream may comprise the manifest data, the indexed metadata and an updated playback position.

In accordance with various embodiments, the first disparate live media output stream for the first client device, such as the client device 132 a, may be altered based on the insertion of the manifest data and indexed metadata in accordance with one of pre-defined conversion modes. The pre-defined conversion modes may correspond to pre-encoded media assets to live stream mode, pre-encoded media assets to live stream mode with scalable architecture, a live stream to live stream mode, and a mixed mode corresponding to switching between pre-encoded media assets and live streams.

At 620B, the manifest data of the first disparate live media output stream manifest may be altered with the programming content associated with the program identifier from a starting point of the programming content when the programming content is eligible for the restart. In accordance with an embodiment, the stream publishing engine 114 in the DACIS 103 may be configured to alter the manifest data of the first disparate live media output stream manifest with the programming content associated with the program identifier from a starting point of the programming content when the programming content is eligible for the restart. Thus, the stream publishing engine 114 may alter the first disparate live media output stream to start playing out the programming content, as specified by the program identifier from the starting point.

Referring back to step 610, in accordance with another embodiment, when the one or more functionalities correspond to the second functionality to skip to a future scheduled programming content in the first disparate live media output stream, control passes to step 626 in the flowchart 600D. In such an embodiment, the second functionality is allowed for a first set of pre-encoded media content or the live input stream that comprises a second set of pre-encoded media content. The program identifier of the programming content may be determined based on a request for a list of programming content, via for example an electronic program guide, associated with the first disparate live media output stream from the repository of schedules, rights, and user preferences database 144. The list of programming content may comprise additional metadata that may control the second functionality of the future scheduled programming content as enabled via the one or more constraints and rights in the published first programming schedule 111.

As the first client device, such as the client device 132 a, plays the first disparate live media output stream returned from the DACIS 103, the user input may be provided to select a future scheduled programming content from the list of programming content (that corresponds to upcoming programming content), in accordance with the second functionality defined in the published first programming schedule 111. In such an embodiment, at least the first client device, such as the client device 132 a, may be configured to determine the program identifier based on selection of the future scheduled programming content from the list of programming content associated with the first disparate live media output stream from the repository of schedules, rights, and user preferences database 144. Thus, the program identifier referenced in the published first programming schedule 111 corresponds to the selected future scheduled programming content that is scheduled to be played out during a future timestamp after a live point in a playback buffer of the first disparate live media output stream.

Based on the user input, the stream publishing engine 114 in the DACIS 103 may be configured to receive the client request from the first client device, such as the client device 132 a, to start the selected future scheduled programming content, in accordance with the second functionality defined in the published first programming schedule 111. The client request thus received, includes the program identifier for the future scheduled programming content to be skipped to and get started with.

At 626, the indexing and storage system 116 may be queried with the received program identifier. In accordance with an embodiment, the stream publishing engine 114 in the DACIS 103 may be configured to query the indexing and storage system 116 with the received program identifier. The stream publishing engine 114 in the DACIS 103 may query the indexing and storage system 116 for an appropriate manifest data and indexed metadata of the programming content associated with the program identifier.

At 628, manifest data and indexed metadata of the programming content associated with the program identifier may be provided back to the stream publishing engine 114. In accordance with an embodiment, the indexing and storage system 116 in the DACIS 103 may be configured to provide the manifest data and indexed metadata of the programming content associated with the program identifier back to the stream publishing engine 114. As discussed above, the manifest data may define at least an associated media content, one or more programming indicators (such as SCTE messages), timing metadata, one or more media content identifiers, and one or more contextual event identifiers. The timing metadata may correspond to the playback position in the published first programming schedule 111.

At 630, it may be determined whether the eligibility of the selected future scheduled programming content is valid against the published first programming schedule 111 for the playback at the time of the client request. In accordance with an embodiment, the stream publishing engine 114 in the DACIS 103 may be further configured to validate against the published first programming schedule 111 that the selected future scheduled programming content is eligible for a playback at a time of the client request. In accordance with an embodiment, the eligibility of the selected future scheduled programming content is determined to be invalid against the published first programming schedule 111 for the playback at the time of the client request, and the control passes to 634. In accordance with another embodiment, the eligibility of the selected future scheduled programming content is determined to be valid against the published first programming schedule 111 for the playback at the time of the client request, and the control passes to 636.

At 632, the client request may be ignored and playback of the first disparate live media output stream is continued at the first client device, such as the client device 132 a, as per the published first programming schedule 111, when the eligibility of the selected future scheduled programming content is determined to be invalid against the published first programming schedule 111 for the playback at the time of the client request. In accordance with an embodiment, the stream publishing engine 114 in the DACIS 103 may be configured to ignore the client request and the playback of the first disparate live media output stream is continued at the first client device, such as the client device 132 a, as per the published first programming schedule 111, when the eligibility of the selected future scheduled programming content is determined to be invalid against the published first programming schedule 111 for the playback at the time of the client request.

At 634, the manifest data and indexed metadata of the programming content associated with the program identifier may be inserted to the first disparate live media output stream manifest in accordance with the second functionality, when the future scheduled programming content is eligible for the playback at the time of the client request. In accordance with an embodiment, the stream publishing engine 114 in the DACIS 103 may be configured to insert the manifest data and indexed metadata of the programming content associated with the program identifier to the first disparate live media output stream manifest in accordance with the second functionality, when the future scheduled programming content is eligible for the playback at the time of the client request.

At 634A, the first disparate live media output stream may be altered based on the insertion of the manifest data and indexed metadata associated with the program identifier referenced in the first programming schedule 111. In accordance with an embodiment, the stream publishing engine 114 in the DACIS 103 may be configured to alter the first disparate live media output stream, based on the insertion of the manifest data and indexed metadata associated with the program identifier referenced in the first programming schedule 111. Such an altered first disparate live media output stream may comprise the manifest data, the indexed metadata and an updated playback position.

In accordance with various embodiments, the first disparate live media output stream for the first client device, such as the client device 132 a, may be altered based on the insertion of the manifest data and indexed metadata in accordance with one of pre-defined conversion modes. The pre-defined conversion modes may correspond to pre-encoded media assets to live stream mode, pre-encoded media assets to live stream mode with scalable architecture, a live stream to live stream mode, and a mixed mode corresponding to switching between pre-encoded media assets and live streams.

At 634B, the selected future scheduled programming content associated with the program identifier in the manifest data, the indexed metadata and the updated playback position, corresponding to a starting point of the selected future scheduled programming, of the altered first disparate live media output stream may be played out. In accordance with an embodiment, the stream publishing engine 114 in the DACIS 103 may be configured to play out the selected future scheduled programming content associated with the program identifier in the manifest data, the indexed metadata and the updated playback position, corresponding to a starting point of the selected future scheduled programming, of the altered first disparate live media output stream. Thus, the stream publishing engine 114 may alter the first disparate live media output stream to start playing out the programming content, as specified by the program identifier from the starting point.

Referring back to step 610, in accordance with another embodiment, when the one or more functionalities include the third functionality to time-shift within the programming content in the first disparate live media output stream, control passes to step 640 in the flowchart 600D. In such an embodiment, the first disparate live media output stream manifest associated with the first disparate live media output stream presented at the client interface of the first client device, such as the client device 132 a, comprises timing metadata. The timing metadata may comprise embedded time-based identifiers corresponding to media segments in the first disparate live media output stream. An example of such time-based identifier may be the one that is defined in HLS by EXT-X-PROGRAM-DATE-TIME tag. However, this example should not be interpreted as causing a departure from the spirit of the present disclosure, and other time-based identifiers may also be incorporated in accordance with incorporation of corresponding streaming protocols.

The program identifier of the programming content may be determined based on a request for a list of programming content, via for example an electronic program guide, associated with the first disparate live media output stream from the repository of schedules, rights, and user preferences database 144. The list of programming content may comprise additional metadata that may control the third functionality which corresponds to each programming content as enabled via the one or more constraints and rights in the published first programming schedule 111.

In accordance with an embodiment, the client interface may be presented at the first client device, such as the client device 132 a, in accordance with the third functionality. Accordingly, in accordance with an embodiment, a seeking option within the programming content in the first disparate live media output stream may be enabled at the client interface of at least the first client device, such as the client device 132 a. The seeking option may be enabled in accordance with a default playback buffer of at least the first client device, such as the client device 132 a, when the programming content that is currently played back does not allow for the third functionality. In other words, if the currently playing programming content does not allow for the third functionality, the client interface may enable seeking within the programming according to the default playback buffer. In accordance with another embodiment, a seeking option within each programming content in the first disparate live media output stream may be enabled at the client interface of at least the first client device, such as the client device 132 a, when the programming content that is currently played back allows for the third functionality. In accordance with an embodiment, the seeking option, such as a seeking operation forwards in time, is enabled within each programming content. The seeking operation forwards in time may be enabled up to a latest published media segment within the first disparate live media output stream manifest. In other words, if the currently playing programming content allows for the third functionality, seeking may be allowed throughout the entirety of the programming content that has been published up to the current live edge by referencing indexed segments that preceded the current playback buffer. In accordance with another embodiment, the seeking option, such as a seeking operation backwards in time, is enabled within each programming content. The seeking operation backwards in time continues into a prior programming content when the seeking operation backwards in time reaches a starting point of the programming content that is currently played back and the third functionality of the prior programming content is enabled. In other words, if the seeking operation backwards in time reaches the beginning of a specific programming content, and the prior programming content before the specific programming content also has time-shifting capability enabled, the seeking operation may continue into the prior programming content. Thus, the seeking operation may continue until a programming content has been reached that does not allow time-shifting or no more programming content is available to seek back to.

As the first client device, such as the client device 132 a, plays the first disparate live media output stream returned from the DACIS 103, the user input may be provided to select one of the above seeking options, such as the seeking operation forwards in time or the seeking operation backwards in time, in accordance with the third functionality defined in the published first programming schedule 111.

Based on the user input, the stream publishing engine 114 in the DACIS 103 may be configured to receive the client request from the first client device, such as the client device 132 a, to time-shift within the programming content in the first disparate live media output stream, in accordance with the third functionality. The client request thus received, includes the program identifier for the programming content (within which the time-shift is to be performed) and a seeking position to which playback is to be time-shifted to.

In accordance with an embodiment, the seeking position may comprise the time-based identifier which may correspond to the embedded time-based identifier, for example, as defined in HLS by the EXT-X-PROGRAM-DATE-TIME tag, within the first disparate live media output stream. In accordance with another embodiment, the seeking position may be calculated based on the embedded time-based identifier associated with a current position of a playhead and a desired duration to seek backwards or forwards in time. For example, the current position of the play head is 07:30 and the desired duration to seek backwards in time is 00.30. Accordingly, the seeking position may be calculated to be 07:00. In another example, the current position of the play head is 07:30 and the desired duration to seek forwards in time is 00.45. Accordingly the seeking position may be calculated to be 07:45. In an embodiment, the seeking position may be calculated at the server-side, i.e. the DACIS 103. In another embodiment, the seeking position may be calculated at the client-side, i.e. the first client device.

At 640, the indexing and storage system 116 may be queried with the received program identifier and the seeking position to which playback is to be time-shifted to. In accordance with an embodiment, the stream publishing engine 114 in the DACIS 103 may be configured to query the indexing and storage system 116 with the received program identifier and the seeking position to which playback is to be time-shifted to. The stream publishing engine 114 in the DACIS 103 may query the indexing and storage system 116 for an appropriate manifest data and indexed metadata of the programming content associated with the program identifier in proximity to the seeking position.

At 642, manifest data and indexed metadata corresponding to the programming content, corresponding to the first programming schedule 111, in proximity to the seeking position for the seeking operation may be determined. In accordance with an embodiment, the indexing and storage system 116 in the DACIS 103 may be configured to determine the manifest data and indexed metadata corresponding to the programming content, corresponding to the first programming schedule 111, in proximity to the seeking position for the seeking operation.

At 644, the determined manifest data and indexed metadata of the programming content associated with the program identifier may be inserted to the first disparate live media output stream manifest in accordance with the third functionality. In accordance with an embodiment, the stream publishing engine 114 in the DACIS 103 may be configured to insert the determined manifest data and indexed metadata of the programming content associated with the program identifier to the first disparate live media output stream manifest in accordance with the third functionality.

At 644A, the first disparate live media output stream may be altered based on the insertion of the determined manifest data and indexed metadata associated with the program identifier referenced in the first programming schedule 111. In accordance with an embodiment, the stream publishing engine 114 in the DACIS 103 may be configured to alter the first disparate live media output stream, based on the insertion of the determined manifest data and indexed metadata associated with the program identifier referenced in the first programming schedule 111. Such an altered first disparate live media output stream may comprise the manifest data, the indexed metadata and an updated playback position.

In accordance with various embodiments, the first disparate live media output stream for the first client device, such as the client device 132 a, may be altered based on the insertion of the manifest data and indexed metadata in accordance with one of pre-defined conversion modes. The pre-defined conversion modes may correspond to pre-encoded media assets to live stream mode, pre-encoded media assets to live stream mode with scalable architecture, a live stream to live stream mode, and a mixed mode corresponding to switching between pre-encoded media assets and live streams.

At 644B, the programming content associated with the program identifier in the manifest data, the indexed metadata and the updated playback position, of the altered first disparate live media output stream may be played out after time-shifting the playback to the seeking position. In accordance with an embodiment, after time-shifting the playback to the seeking position, the stream publishing engine 114 in the DACIS 103 may be configured to play out the programming content associated with the program identifier in the manifest data, the indexed metadata and the updated playback position, of the altered first disparate live media output stream. The altered first disparate live media output stream may be viewed at the first client device, such as the client device 132 a.

Referring back to step 610, in accordance with another embodiment, when the one or more functionalities include the fourth functionality to resume playback within the programming content in the first disparate live media output stream, control passes to step 650 in the flowchart 600E. In such an embodiment, the first disparate live media output stream manifest associated with the first disparate live media output stream comprises timing metadata. The timing metadata may comprise embedded time-based identifiers corresponding to media segments in the first disparate live media output stream. An example of such time-based identifier may be the one that is defined in HLS by EXT-X-PROGRAM-DATE-TIME tag. However, this example should not be interpreted as causing a departure from the spirit of the present disclosure, and other time-based identifiers may also be incorporated in accordance with incorporation of corresponding streaming protocols.

In accordance with an embodiment, the client interface may be presented at the first client device, such as the client device 132 a, in accordance with the fourth functionality which corresponds to each programming content as enabled via the one or more constraints and rights. The first client device, such as the client device 132 a, may proceed to playback the first disparate live media output stream. As the playback occurs, the first client device, such as the client device 132 a, remains updated about the current playback time as provided by the embedded time-based identifiers in the timing metadata corresponding to media segments in the first disparate live media output stream.

As the first disparate live media output stream is played back at the first client device, such as the client device 132 a, a user input may be provided, which may correspond to a pause operation or a termination operation of the playback of the first disparate live media output stream at the first client device, such as the client device 132 a.

Based on the pause operation or a termination operation, a stream identifier of the first disparate live media output stream, the program identifier of the programming content that is currently playing back, and the timing metadata within the first disparate live media output stream may be captured by at least the first client device, such as the client device 132 a. In accordance with various embodiments, the first client device, such as the client device 132 a may be configured to store the captured stream identifier, the program identifier, and the timing metadata in one or more of at least the first client device, such as the client device 132 a, associated with a user identifier, a server associated with the user identifier, or the repository of schedules, rights, and user preferences database 144. The stream identifier, the program identifier, and the timing metadata, thus stored, may correspond to a bookmark identifier that may define a state of the first disparate live media output stream. In accordance with an embodiment, the user identifier may correspond to a user associated with at least the first client device, such as the client device 132 a.

At 650, a client request may be received from the first client device, such as the client device 132 a, or the second client device, such as the client device 132 b, to resume playback of the first disparate live media output stream on at least one of the first client device, such as the client device 132 a, or the second client device, such as the client device 132 b. In accordance with an embodiment, the stream publishing engine 114 in the DACIS 103 may be configured to receive the client request from the first client device, such as the client device 132 a, or the second client device, such as the client device 132 b, to resume playback of the first disparate live media output stream on at least one of the first client device, such as the client device 132 a, or the second client device, such as the client device 132 b. The received client request may correspond to a user selection to resume playback of the first disparate live media output stream on at least one of the first client device, such as the client device 132 a, or a second client device, such as the client device 132 b. In such an embodiment, the user identifier of the first client device, such as the client device 132 a, may be further associated with the second client device, such as the client device 132 b. In such embodiment, the client request may comprise the stream identifier of the first disparate live media output stream, the program identifier of the programming content that is currently playing back, and the timing metadata within the first disparate live media output stream.

At 652, it may be checked if programming content that is currently played back allows for fourth functionality. In accordance with an embodiment, the stream publishing engine 114 in the DACIS 103 may be configured to check if the programming content that is currently played back allows for fourth functionality. In an embodiment, when the programming content that is currently played back does not allow for the fourth functionality, control passes to 654. In another embodiment, when the programming content that is currently played back allows for the fourth functionality, control passes to 656.

At 654, playout of the programming content may be proceeded from live point. In accordance with an embodiment, the stream publishing engine 114 in the DACIS 103 may be configured to proceed with the playout of the programming content from live point.

At 656, the first programming schedule 111 may be determined from a set of programming schedules associated with the stream identifier based on the timing metadata in the client request. In accordance with an embodiment, the stream publishing engine 114 in the DACIS 103 may be configured to determine the first programming schedule 111 from the set of programming schedules associated with the stream identifier from the indexing and storage system 116 based on the timing metadata in the client request. In other words, the stream publishing engine 114 may look up prior programming schedules that are associated with the stream identifier and scheduled during the timing metadata from the indexing and storage system 116.

At 658, an altered schedule may be checked. In accordance with an embodiment, the stream publishing engine 114 in the DACIS 103 may be configured to check for an altered schedule. In an embodiment, for an altered schedule, control passes to 660. In another embodiment, for the same schedule, that is the first programming schedule 111, control passes to 668.

At 660, an alternate representation of the first disparate live media output stream may be determined based on the repository of schedules, rights, and user preferences database 144 or third-party systems. In accordance with an embodiment, the stream publishing engine 114 in the DACIS 103 may be configured to determine an alternate representation of the first disparate live media output stream based on the repository of schedules, rights, and user preferences database 144 or third-party systems. In accordance with an embodiment, the determined alternate representation of the first disparate live media output stream may be optimized for another client device, i.e. at least the second client device, such as the client device 132 b, when the client request is generated at the first client device, such as the client device 132 a. For example, in case the first disparate live media output stream is paused at the client device 132 a, such as a tablet, and the playback is requested to be resumed on the client device 132 b, such as a mobile client, the stream publishing engine 114 may elect to generate an altered schedule to reconstruct the first disparate live media output stream optimized for mobile playback. In accordance with another embodiment, the determined alternate representation of the first disparate live media output stream may comprise non-programming content targeted for one or more users associated with one or both of the first client device, such as the client device 132 a, and the second client device, such as the client device 132 b. For example, in case the first disparate live media output stream is paused at the client device 132 a, such as a mobile client, and the playback is requested to be resumed on the client device 132 b, such as a television screen, known to be used by multiple users, the stream publishing engine 114 may elect to generate an altered schedule to reconstruct the first disparate live media output stream for the client device 132 b known to be used by multiple users. Accordingly, additional advertising or promotional content may be included and targeted for the multiple users associated with the client device 132 b.

At 662, the first disparate live media output stream may be reconstructed and a second disparate live media output stream may be generated based on an insertion of manifest data and indexed metadata of the programming content associated with the program identifier referenced in altered schedule, in addition to stream identifier and timing metadata. In accordance with an embodiment, the stream publishing engine 114 in the DACIS 103 may be configured to reconstruct the first disparate live media output stream and generate a second disparate live media output stream based on the insertion of the manifest data and indexed metadata of the programming content associated with the program identifier referenced in altered schedule, in addition to stream identifier and timing metadata.

At 664, programming content associated with the program identifier in the manifest data, indexed metadata and updated playback position, of the second disparate live media output stream may be played out. In accordance with an embodiment, the stream publishing engine 114 in the DACIS 103 may be configured to play out the programming content associated with the program identifier in the manifest data, indexed metadata and updated playback position, of the second disparate live media output stream. The generated second disparate live media output stream may be viewed at one or both of the first client device, such as the client device 132 a, and the second client device, such as the client device 132 b, in response to the generated client request.

At 666, for an unaltered schedule, the manifest data and the indexed metadata of the programming content associated with the program identifier may be inserted to the first disparate live media output stream manifest in accordance with the fourth functionality. In accordance with an embodiment, the stream publishing engine 114 in the DACIS 103 may be configured to insert the manifest data and the indexed metadata of the programming content associated with the program identifier to the first disparate live media output stream manifest in accordance with the fourth functionality.

At 668, a second disparate live media output stream may be generated, based on the insertion of the manifest data and indexed metadata associated with the program identifier referenced in the first programming schedule 111, in addition to the stream identifier and the timing metadata. In accordance with an embodiment, the stream publishing engine 114 in the DACIS 103 may be configured to generate the second disparate live media output stream, based on the insertion of the manifest data and indexed metadata associated with the program identifier referenced in the first programming schedule 111, in addition to the stream identifier and the timing metadata. Such a generated second disparate live media output stream may comprise the manifest data, the indexed metadata, and the updated playback position for resuming at one or both of the first client device, such as the client device 132 a, and the second client device, such as client device 132 b, as requested. For example, the timing metadata of the user input (a terminate operation) at the client device 132 a is 07:00:01 and the timing metadata of the client request at the client device 132 b is 07:30:03. In such an embodiment, the manifest data and indexed metadata associated with the program identifier may also include the programming content of a duration of 00:30:02 hours that was lapsed after the user input was provided at the client device 132 a to terminate the first disparate live media output stream. The updated playback position may be set accordingly in the generated second disparate live media output stream manifest.

In accordance with an embodiment, the stream publishing engine 114 in the DACIS 103 may be configured to generate an altered first disparate live media output stream, based on the insertion of the determined manifest data and indexed metadata associated with the program identifier referenced in the first programming schedule 111, in addition to the stream identifier and the timing metadata. Such altered first disparate live media output stream may comprise the manifest data, the indexed metadata, and the updated playback position for resuming at one or both of the first client device, such as the client device 132 a, and the second client device, such as client device 132 b, as requested. For example, the timing metadata of the user input (a pause operation) at the client device 132 a indicates 07:00:01 and the timing metadata of the client request at the client device 132 b indicates 07:00:03. In such an embodiment, the updated playback position may be set accordingly in the altered first disparate live media output stream manifest.

In accordance with various embodiments, the second disparate live media output stream for the first client device, such as the client device 132 a, or the second client device, such as the client device 132 b, may be generated based on one of the pre-defined conversion modes. The pre-defined conversion modes may correspond to pre-encoded media assets to live stream mode, pre-encoded media assets to live stream mode with scalable architecture, a live stream to live stream mode, and a mixed mode corresponding to switching between pre-encoded media assets and live streams.

At 670, the programming content associated with the program identifier in the manifest data, the indexed metadata and the updated playback position, of the generated second disparate live media output stream may be played out. In accordance with an embodiment, the stream publishing engine 114 in the DACIS 103 may be configured to play out the programming content associated with the program identifier in the manifest data, the indexed metadata and the updated playback position, of the second disparate live media output stream. The second disparate live media output stream may be viewed at one or both of the first client device, such as the client device 132 a, and the second client device, such as the client device 132 b, in response to the generated client request.

In accordance with an embodiment, the second set of processors in the DACIS 103 may be further configured to retrieve the indexed metadata associated with the selected one or more live input streams and/or the one or more pre-encoded media assets from the CPDS 107. The associated indexed metadata may define one or more content placement opportunities within the selected one or more live input streams and/or the one or more pre-encoded media assets. The customized first programming content and the targeted first non-programming content may be identified as the first additional content to be scheduled at the one or more content placement opportunities based on the one or more parameters in the received first manifest request and the associated indexed metadata, wherein the generated first programming schedule 111 excludes the first additional content or includes the first additional content completely or partially.

In accordance with an embodiment, a third set of processors in the DACIS 103 may be further configured to insert, based on the generated first programming schedule 111, the identified customized first programming content and the targeted first non-programming content into the first disparate live media output stream manifest in accordance with the one or more content placement opportunities defined in the associated indexed metadata and one or more rules and conditions defined in the repository of schedules, rights, and user preferences database 144. The identification of the targeted first non-programming content may be based on execution of a non-programming content service based on rules and conditions defined in additional parameters of the repository of schedules, rights, and user preferences database 144, and the one or more parameters defined in the first manifest request. The identification of the customized first programming content may be based on execution of the CDS 105 based on the rules and conditions defined in the additional parameters of the repository of schedules, rights, and user preferences database 144. In accordance with an embodiment, the first programming schedule 111 may define locations and types of one or more decision points defined by one or more content placement opportunities in the indexed metadata. In an instance when one or more pre-encoded media assets are being scheduled and the one or more decision points defined by the one or more content placement opportunities are to be inserted in the first programming schedule 111, the first programming schedule 111 may be configured to control the one or more pre-encoded media asset manifests to be published as the first disparate live media output stream manifest.

In accordance with an embodiment, a conversion of one or more pre-encoded media assets into a first disparate live media output stream facilitates one or more subsequent modifications on the first disparate live media output stream.

In accordance with an embodiment, the first set of processors in the DACIS 103 may be further configured to transmit universal resource locators and/or identifiers referencing records for the selected one or more live input streams and/or the one or more pre-encoded media assets to the second set of processors. In an absence of one or more live input streams, the first set of processors may be configured to select a pre-encoded asset indicated in the first manifest request to continue playback as the first disparate live media output stream. The second set of processors may be configured to select a second disparate live media output stream according to accessibility of the first disparate live media output stream. The first disparate live media output stream is not updated and/or the first disparate live media output stream has media and/or a manifest that is incompatible with a client request. The second set of processors may be further configured to select the second disparate live media output stream according to rules provided by a stream owner/operator and user preferences defined in the repository of schedules, rights, and user preferences database 144.

In accordance with an embodiment, the one or more processors in the DACIS 103 may be further configured to transition from the first additional content to an alternate additional content based on one or more transition parameters. The one or more transition parameters may comprise one or more parameters from the first manifest request, current state of the first disparate live media output stream manifest determined based on accessibility, regular update, and suitable encoding, digital rights management, and compatibility with the first client device, rules provided by a stream owner operator, and user preferences defined in the repository of schedules, rights, and user preferences database 144.

In accordance with an embodiment, the one or more processors in the DACIS 103 may be further configured to retrieve alternate metadata for the alternate additional content from the CPDS 107. The alternate metadata may indicate a location to transition from the first additional content to the alternate additional content. The one or more processors may be further configured to determine placement of the alternate additional content within the first disparate live media output stream manifest based on the associated indexed metadata and the alternate metadata. The one or more processors may be further configured to generate the alternate programming schedule 113, for the first client device based on the alternate additional content and the alternate metadata, and transmit the generated alternate programming schedule to the first set of processors. The first set of processors may be configured to generate a final disparate live output stream manifest for the first client device. In accordance with an embodiment, another conversion of the first disparate live media output stream into the one or more pre-encoded media assets facilitates download of the one or more pre-encoded media assets at the first client device and mitigates dependency on the system for playback of remaining portion. In accordance with an embodiment, the one or more processors in the DACIS 103 may be further configured to receive a request from the first client device, wherein the request comprises the one or more parameters. The one or more processors in the DACIS 103 may be further configured to determine alternate additional content for inclusion in the first disparate live media output stream manifest or replacement of the first additional content in the first disparate live media output stream manifest based on the one or more parameters. The one or more processors in the DACIS 103 may be further configured to modify the first programming schedule 111 to generate an alternate programming schedule for the first client device based on the alternate additional content and associated metadata. The one or more processors in the DACIS 103 may be further configured to transmit the generated alternate programming schedule to a second set of processors, wherein the second set of processors is configured to generate a final disparate live output stream manifest for the first client device.

In accordance with an embodiment, the one or more processors in the DACIS 103 may be further configured to revoke the first disparate live media output stream manifest published for the first client device based on an identifier primitive associated with the first disparate live media output stream of the first client device in an instance in which a media player of the first client device is determined to be a plagiarized media player. The first disparate live media output stream may include at least one unique identifier inserted by the one or more processors n the DACIS 103.

In accordance with various embodiments, the first disparate live media output stream manifest for the first client device may be generated based on one of a pre-defined conversion modes. The pre-defined conversion modes may correspond to pre-encoded media assets to live stream mode, pre-encoded media assets to live stream mode with scalable architecture, a live stream to live stream mode, and a mixed mode corresponding to switching between pre-encoded media assets and live streams.

In accordance with an embodiment, one or more processors in the PEM 115 may be configured to receive a first manifest request, comprising one or more parameters, from the first client device. Further, the received first manifest request may be transmitted to a first set of processors in the stream selection service 142. The first set of processors may be configured to select, based on the received first manifest request, one or more live input streams and/or one or more pre-encoded media assets based on the one or more parameters and additional parameters retrieved from the repository of schedules, rights, and user preferences database 144. The one or more processors in the PEM 115 may be configured to receive universal resource locators and/or identifiers referencing records for the selected one or more live input streams and/or the one or more pre-encoded media assets from the first set of processors. The one or more processors in the PEM 115 may be configured to retrieve indexed metadata associated with the selected one or more live input streams and/or the one or more pre-encoded media assets from a content packaging and distribution system, wherein the indexed metadata defines one or more content placement opportunities within the selected one or more live input streams and/or the one or more pre-encoded media assets. The one or more processors in the PEM 115 may be further configured to identify a customized first programming content and a targeted first non-programming content as a first additional content to be scheduled in the one or more content placement opportunities based on the one or more parameters in the received first manifest and the associated indexed metadata.

In accordance with an embodiment, the one or more functionalities enabled via the one or more constraints and rights include a second functionality to skip to a future scheduled programming content in the first disparate live media output stream. The second functionality may be allowed for a first set of pre-encoded media content or a live input stream that comprises a second set of pre-encoded media content.

A list of programming content associated with the first disparate live media output stream from a repository of schedules, rights, and user preferences database may be requested by the first client device, such as the client device 132 a. The list of programming content may comprise additional metadata that controls the second functionality of the future scheduled programming content as enabled via the one or more constraints and rights in the published first programming schedule 111. In such an embodiment, the client request may be generated by the first client device, such as the client device 132 a, based on a user input that may correspond to a selection of the future scheduled programming content from the list of programming content. The program identifier referenced in the published first programming schedule 111 may correspond to the selected future scheduled programming content that is scheduled to be played out during a future timestamp after a live point in a playback buffer of the first disparate live media output stream. Further, the one or more processors in the DACIS 103, such as the stream publishing engine 114, may be configured to validate against the published first programming schedule 111 that the selected future scheduled programming content is eligible for playback at a time of the client request. In accordance with an embodiment, the one or more processors in the DACIS 103, such as the stream publishing engine 114, may be configured to ignore the client request when the selected future scheduled programming content is ineligible for playback at the time of the client request. Further, the playback of the first disparate live media output stream may be continued at the first client device, such as the client device 132 a, as per the published first programming schedule 111.

In accordance with another embodiment, the one or more functionalities enabled via the one or more constraints and rights include a third functionality to time-shift within the programming content in the first disparate live media output stream. The first disparate live media output stream manifest associated with the first disparate live media output stream presented at the first client device, such as the client device 132 a, may comprise timing metadata. The timing metadata may comprise embedded time-based identifiers corresponding to media segments in the first disparate live media output stream. Further, a list of programming content associated with the first disparate live media output stream from a repository of schedules, rights, and user preferences database is requested by the first client device, such as the client device 132 a. The list of programming content may comprise additional metadata that controls the third functionality which corresponds to each programming content as enabled via the one or more constraints and rights in the published first programming schedule 111. A client interface may be presented at the first client device, such as the client device 132 a, in accordance with the third functionality which corresponds to each programming content as enabled via the one or more constraints and rights. A seeking option within the programming content in the first disparate live media output stream may be enabled at the client interface of at least the first client device, such as the client device 132 a, in accordance with a default playback buffer of at least the first client device, such as the client device 132 a, when the programming content that is currently played back does not allow for the third functionality. In another embodiment, the seeking option within each programming content in the first disparate live media output stream may be enabled at the client interface of at least the first client device, such as the client device 132 a, when the programming content that is currently played back allows for the third functionality. Such seeking option is enabled within each programming content and a seeking operation forwards in time is up to a latest published media segment within the first disparate live media output stream manifest. The client request may further comprise a seeking position to which playback is to be time-shifted to. A seeking operation continues into a prior programming content when the seeking operation backwards in time reaches a starting point of the programming content that is currently played back and the third functionality of the prior programming content is enabled. In an embodiment, the seeking position may comprise a time-based identifier which corresponds to an embedded time-based identifier within the first disparate live media output stream. In another embodiment, the seeking position may be calculated based on an embedded time-based identifier associated with a current position of a playhead and a desired duration to seek backward or forward.

The one or more processors in the DACIS 103, such as the stream publishing engine 114, may be configured to determine the manifest data and indexed metadata corresponding to the programming content, corresponding to the first programming schedule 111, in proximity to the seeking position for the seeking operation. The altered first disparate live media output stream to be viewed by at least the first client device, such as the client device 132 a, may be generated by the one or more processors, such as the stream publishing engine 114, based on the insertion of the determined manifest data and indexed metadata.

In accordance with another embodiment, the one or more functionalities enabled via the one or more constraints and rights include a fourth functionality to resume playback within the programming content in the first disparate live media output stream. The first disparate live media output stream manifest associated with the first disparate live media output stream presented on at least the first client device, such as the client device 132 a, may comprise timing metadata. The timing metadata may comprise embedded time-based identifiers.

In an embodiment, a playback of the first disparate live media output stream may be paused or terminated by at least the first client device, such as the client device 132 a. A stream identifier of the first disparate live media output stream, the program identifier of the programming content that is currently playing back, and timing metadata within the first disparate live media output stream may be captured by at least the first client device, such as the client device 132 a. The captured stream identifier, the program identifier, and the timing metadata may be stored in one or more of at least the first client device, such as the client device 132 a, a server associated with a user identifier, or a repository of schedules, rights, and user preferences database. The user identifier may correspond to a user associated with at least the first client device, such as the client device 132 a. The stored stream identifier, the program identifier, and the timing metadata may correspond to a bookmark identifier that defines a state of the first disparate live media output stream. In such case, the client request may correspond to a user selection to resume playback of the first disparate live media output stream on at least one of the first client device, such as the client device 132 a, or a second client device, such as client device 132 b. The user identifier of the first client device, such as the client device 132 a, may be further associated with the second client device, such as client device 132 b. Thus, the client request further comprises the stream identifier and the timing metadata in addition to the program identifier.

The one or more processors in the DACIS 103, such as the stream publishing engine 114, may be configured to determine the first programming schedule 111 from a set of programming schedules associated with the stream identifier based on the timing metadata in the client request, and reconstruct the first disparate live media output stream for the altered schedule associated with the stream identifier, the program identifier, and the timing metadata. In accordance with an embodiment, the reconstructed first disparate live media output stream corresponds to the second disparate live media output stream, and the generated second disparate live media output stream is viewed at one or both of the first client device and the second client device

The one or more processors in the DACIS 103, such as the stream publishing engine 114, may be configured to determine an alternate representation of the first disparate live media output stream from the repository of schedules, rights, and user preferences database 144 or third-party systems. In an embodiment, the determined alternate representation of the first disparate live media output stream may be optimized for at least the second client device, such as client device 132 b. In accordance with an embodiment, the determined alternate representation of the first disparate live media output stream comprises non-programming content targeted for one or more users associated with one or both of the first client device, such as the client device 132 a, and the second client device, such as client device 132 b.

Various embodiments of the disclosure may provide a computer-readable medium, such as the non-transitory computer-readable medium 506, having stored thereon, computer implemented instruction that when executed by the processor 504 causes the media packaging and distribution system 102 to execute operations for publishing a disparate per-client live media output stream based on dynamic insertion of targeted non-programming content and customized programming content. In accordance with an embodiment, the processor 504 causes the media packaging and distribution system 102 to execute operations to receive a first manifest request, comprising one or more parameters, from a first client device, such as client device 132 a. The processor 504 causes the media packaging and distribution system 102 to execute operations to determine a first additional content comprising a customized first programming content and a targeted first non-programming content for the first client device based on the one or more parameters and associated indexed metadata retrieved based on the one or more parameters. The processor 504 causes the media packaging and distribution system 102 to execute operations to generate the first programming schedule 111, for the first client device based on selected one or more live input stream and/or the one or more pre-encoded media assets, the associated indexed metadata, and the determined first additional content. The processor 504 causes the media packaging and distribution system 102 to execute operations to select one or more live input stream manifests and/or one or more pre-encoded media asset manifests published in the content delivery system 130 and associated indexed metadata based on the one or more parameters. The processor 504 causes the media packaging and distribution system 102 to execute operations to publish a first disparate live media output stream manifest for the first client device based on insertion of the selected one or more live input stream manifests and/or the one or more pre-encoded media asset manifests, the associated indexed metadata, and the determined first additional content in accordance with the first programming schedule 111, generated for the first client device.

Various embodiments of the disclosure may provide a computer-readable medium, such as the non-transitory computer-readable medium 506, having stored thereon, computer implemented instruction that when executed by the processor 504 causes the media packaging and distribution system 102 to execute operations for server-side dynamic insertion of programming content in an indexed disparate live media output stream. In accordance with an embodiment, the processor 504 causes the media packaging and distribution system 102 to execute operations to publish a first programming schedule that may comprise one or more functionalities enabled via one or more constraints and rights associated with at least a first disparate live media output stream. The published first programming schedule may reference one or more pre-encoded media assets and/or one or more live input streams. The processor 504 causes the media packaging and distribution system 102 to execute operations to generate an indexed first disparate live media output stream for a first client device based on the published first programming schedule. The processor 504 causes the media packaging and distribution system 102 to execute operations to receive a client request from the first client device based on a playback of the indexed first disparate live media output stream at the first client device. The client request comprises at least a program identifier referenced in the published first programming schedule with respect to a playback position in the published first programming schedule. The processor 504 causes the media packaging and distribution system 102 to execute operations to insert manifest data and indexed metadata of a programming content associated with the program identifier to a first disparate live media output stream manifest in accordance with the one or more functionalities. The processor 504 causes the media packaging and distribution system 102 to execute operations to at least one of alter the first disparate live media output stream or generate a second disparate live media output stream, based on the insertion of the manifest data and indexed metadata associated with the program identifier referenced in the first programming schedule. The altered first disparate live media output stream or the generated second disparate live media output stream comprises the manifest data, the indexed metadata and an updated playback position.

Existing systems for SSAI support live streaming and make decisions to insert non-programing content in near real-time. However, for On-Demand streaming, such decisions to insert non-programing content are made upfront. Further, legacy technology of the existing systems for server-side content insertion support a finite playback buffer as the encoder typically publishes a rolling window having limited duration. Accordingly, amount of control the user can excerpt to influence what non-programming content and programming content is shown may get limited. Further, newer ad models are developing that rely less on interruptive video advertising and more on contextual based graphical treatment advertising within the program content. To this extent, SSAI systems have been able to circumvent ad blockers by requesting video ads on behalf of the client device and stitching them into the disparate live media output stream manifest.

To address at least the above problems, in accordance with the various embodiments of the present disclosure, the DACIS 103 in the media packaging and distribution system 102 may be configured to include not showing non-programming content that the user elected to skip or rated poorly in an earlier non-programming content break, or could enable the user to skip all non-programming content because the user interacted with an previous non-programming content or made a purchase and the advertiser elected to sponsor the remainder of the program.

The DACIS 103 may notified about graphical treatment opportunities within the content, make the necessary ad calls on behalf of the client device, and provide the client device with the information needed to execute the overlays via a secure out-of-band channel between the DACIS 103 and the client device. In many cases, a channel already exists to support passing the program indicators, such as start and end information, to the client device and Video Player Ad-Serving Interface (VPAID) ads that cannot be stitched.

The DACIS 103 may also provide an opportunity to leverage the 1:1 scale of traditional SSAI systems to support custom content choices and not just targeted advertising. For example, when a user selects to join a live stream, the CDS 105 coupled with the DACIS 103 may determine that, instead of joining the live stream for the last few minutes of a program, the user should instead be shown content more relevant to the next program. For example, showing a personalized set of basketball highlights and ads to a user who likely joined the stream to watch the basketball game that is coming on next.

Further, the DACIS 103 may be used to provide seamless failover between redundant streams for large events, thus improving reliability. While some client devices support primary and backup streams and are able to fail between them, many client devices do not. In such cases, the client device may attempt to join the alternative stream after occurrence of an event, such as a device failure or crash. For such clients, the DACIS 103 monitors both the primary and backup stream, and if there is a failure, inserts the alternative stream into the output manifest. Thus, the media packaging and distribution system 102 provides an enhanced, intelligent, and personalized viewer experience with increased appeal in order to retain and gain a wider audience.

Furthermore, the DACIS 103 may allow the simulation of an infinite live window (or an infinite playback buffer). Accordingly, the user may seek to a desired point scheduled backwards or forwards with respect to a live point in a playback buffer of the first disparate live media output stream, limited by business rules. To simulate “rewinding” beyond what is currently defined in the buffer, the first disparate live media output stream may cease to play out the next sequence of media and instead elect to have the next appended media segment in the first disparate live media output stream be the desired media segment, which is either previously played out or to be played out, at the desired time. Furthermore, there is no need to store the state of the first disparate live media output stream play out on a moment-to-moment basis, but rather what entire programming content was played and at what date/time. Only parameters necessary to reconstruct the state of the first disparate live media output stream from any moment are stream identifier, which is correlated to one or more schedules of programs, program identifier, and timing metadata of desired playback time.

In certain cases, the system may be enabled to seek the playhead ahead or behind a playout window of a disparate live media output stream, which may result in an updated playout buffer. Further, the system may enable a saved scheduled state that comprises stream identifier, program identifier, time identifier, and associated programming schedule, based on which the disparate live media output stream may be reconstructed to represent the exact or slightly altered disparate live media output stream from the past.

The DACIS 103, the CDS 105, the CPDS 107, the stream publishing engine 114, PEM 115, indexing and storage system 116, the stream selection service 142, and the repository of schedules, rights, and user preferences database 144 in conjunction with each other, provide significant productivity and efficiency improvements since the process of generating disparate live media output streams with additional content is specific to each consumer device. The disparate live media output streams are simplified as the generated disparate live media output streams are independent of a requirement to re-process, that is re-encode and re-package, various live input streams for media distribution to the plurality of consumer devices in real time or near-real time. Thus, the network provider now may provide live channel offerings in a cost-effective manner.

Various components, as described above in FIG. 1B, enable the media packaging and distribution system 102 to leverage the modern streaming protocols, based on which the media packaging and distribution system 102 generates disparate live media output streams of the live broadcast channels with additional content and one or more decision points to influence the remaining disparate live media output streams. The disparate live media output streams may be generated based on insertion of live input streams into a generated disparate live media output stream using pre-encoded media assets. In this regard, manifests from the live input streams and the pre-encoded media assets may be manipulated and produced for distribution of the disparate live media output stream.

As the media content itself does not need to be processed beyond the initial creation of the live input streams and pre-encoded media assets prepared for distribution, it is extremely inexpensive to provide such disparate live media output streams and alternate disparate live media output stream (in case of stream failover). It may be based solely on the cost to manipulate the manifests, which provide the instructions for the media players in the client devices 132 a, . . . , 132 n to execute. The media packaging and distribution system 102 may also support targeted ad insertion and customized programming content insertion on a per client basis and may further leverage the processing power of the individual client devices 132 a, . . . , 132 n to insert targeted channel graphics and graphical treatment advertisements and promotions.

The media packaging and distribution system 102 may also support unique functionality where the disparate live media output stream is required to effectively be re-stitched/rebuilt in real-time using indexed pre-encoded media assets or live input stream assets according to the time-shifting request originating from the user. The method described herein have additional benefits as such methods are optimized for scale and are extremely efficient. Having no need to store the state of the disparate live media output stream playout in a moment-to-moment basis, but rather what entire programming content was played and what date/time, as well as having each program that was played out indexed indefinitely in the indexing and storage system 116, the only parameters necessary to reconstruct the state of the disparate live media output stream from any moment are stream identifier, which is correlated to one or more published schedules of the programming content, program identifier, and timing metadata of desired playback time. The timing metadata plays a key role in the reconstruction, as it determines the precise schedule and position within the desired programming to begin playout.
